-Enzo Parameter List
-The following is a largely complete list of the parameters that Enzo
-understands, and a brief description of what they mean. They are grouped
-roughly by meaning; an alphabetical list is also available. Parameters for
-individual test problems are also listed here.
-This parameter list has two purposes. The first is to describe and explain the
-parameters that can be put into the initial parameter file that begins a run.
-The second is to provide a comprehensive list of all parameters that the code
-uses, including those that go into an output file (which contains a complete
-list of all parameters), so that users can better understand these output
-The parameters fall into a number of categories:
-    These are user parameters in the sense that they can be set in the
-    parameter file, and provide the primary means of communication
-    between Enzo and the user.
-    These are mostly not set in the parameter file (although strictly
-    speaking they can be) and are generally used for program to
-    communicate with itself (via the restart of output files).
-    No longer used.
-    To be used later.
-Generally the external parameters are the only ones that are modified or set,
-but the internal parameters can provide useful information and can sometimes be
-modified so I list them here as well. Some parameters are true/false or on/off
-boolean flags.  Eventually, these may be parsed, but in the meantime, we use the
-common convention of 0 meaning false or off and 1 for true or on.
-This list includes parameters for the Enzo 2.0 release.
-.. highlight:: none
-Stopping Parameters
-``StopTime`` (external)
-    This parameter specifies the time (in code units) when the
-    calculation will halt. For cosmology simulations, this variable is
-    automatically set by ``CosmologyFinalRedshift``. *No default.*
-``StopCycle`` (external)
-    The cycle (top grid timestep) at which the calculation stops. A
-    value of zero indicates that this criterion is not be used.
-    *Default: 100,000*
-``StopFirstTimeAtLevel`` (external)
-    Causes the simulation to immediately stop when a specified level is
-    reached. Default value 0 (off), possible values are levels 1
-    through maximum number of levels in a given simulation.
-``NumberOfOutputsBeforeExit`` (external)
-    After this many datadumps have been written, the code will exit.  If 
-    set to 0 (default), this option will not be used.  Default: 0.
-``StopCPUTime`` (external)
-    Causes the simulation to stop if the wall time exceeds ``StopCPUTime``.
-    The simulation will output if the wall time after the next
-    top-level timestep will exceed ``StopCPUTime``, assuming that the wall
-    time elapsed during a top-level timestep the same as the previous
-    timestep. In units of seconds. Default: 2.592e6 (30 days)
-``ResubmitOn`` (external)
-    If set to 1, the simulation will stop if the wall time will exceed
-    ``StopCPUTime`` within the next top-level timestep and run a shell
-    script defined in ``ResubmitCommand`` that should resubmit the job
-    for the user. Default: 0.
-``ResubmitCommand`` (external)
-    Filename of a shell script that creates a queuing (e.g. PBS)
-    script from two arguments, the number of processors and parameter
-    file.  This script is run by the root processor when stopping with
-    ``ResubmitOn``. An example script can be found in
-    input/ Default: (null)
-Initialization Parameters
-``ProblemType`` (external)
-    This integer specifies the type of problem to be run. Its value
-    causes the correct problem initializer to be called to set up the
-    grid, and also may trigger certain boundary conditions or other
-    problem-dependent routines to be called. The possible values are
-    listed below. Default: none. 
-For other problem-specific parameters follow the links below.  The problems
-marked with "hydro_rk" originate from the MUSCL solver package in the enzo installation directory
-``src/enzo/hydro_rk``.  For the 4xx radiation hydrodynamics problem types, see
-the user guides in the installation directory ``doc/implicit_fld`` and ``doc/split_fld``.

-``TopGridRank`` (external)
-    This specifies the dimensionality of the root grid and by extension
-    the entire hierarchy. It should be 1,2 or 3. Default: none
-``TopGridDimensions`` (external)
-    This is the dimension of the top or root grid. It should consist of
-    1, 2 or 3 integers separated by spaces. For those familiar with the
-    KRONOS or ZEUS method of specifying dimensions, these values do not
-    include ghost or boundary zones. A dimension cannot be less than 3
-    zones wide and more than ``MAX_ANY_SINGLE_DIRECTION`` -
-    ``NumberOfGhostZones``\*2. ``MAX_ANY_SINGLE_DIRECTION`` is defined in
-    ``fortran.def``. Default: none
-``DomainLeftEdge``, ``DomainRightEdge`` (external)
-    These float values specify the two corners of the problem domain
-    (in code units). The defaults are: 0 0 0 for the left edge and 1 1
-    1 for the right edge.
-``LeftFaceBoundaryCondition``, ``RightFaceBoundaryCondition`` (external)
-    These two parameters each consist of vectors of integers (of length
-    ``TopGridRank``). They specify the boundary conditions for the top grid
-    (and hence the entire hierarchy). The first integer corresponds to
-    the x-direction, the second to the y-direction and the third, the
-    z-direction. The possible values are: 0 - reflecting, 1 - outflow,
-    2 - inflow, 3 - periodic, 4 - shearing. For inflow, the inflow
-    values can be set through the next parameter, or more commonly are
-    controlled by problem-specific code triggered by the ``ProblemType``.
-    For shearing boundaries, the boundary pair in another direction
-    must be periodic. Note that self gravity will not be consistent
-    with shearing boundary conditions. Default: 0 0 0
-``ShearingVelocityDirection`` (external)
-    Select direction of shearing boundary. Default is x direction. Changing this is probably not a good idea.
-``AngularVelocity`` (external)
-    The value of the angular velocity in the shearing boundary.
-    Default: 0.001
-``VelocityGradient`` (external)
-    The value of the per code length gradient in the angular velocity
-    in the shearing boundary. Default: 1.0
-``BoundaryConditionName`` (external)
-    While the above parameters provide an easy way to set an entire
-    side of grid to a given boundary value, the possibility exists to
-    set the boundary conditions on an individual cell basis. This is
-    most often done with problem specific code, but it can also be set
-    by specifying a file which contains the information in the
-    appropriate format. This is too involved to go into here. Default:
-    none
-``InitialTime`` (internal)
-    The time, in code units, of the current step. For cosmology the
-    units are in free-fall times at the initial epoch (see :ref:`EnzoOutputFormats`). Default: generally 0, depending on problem
-``Initialdt`` (internal)
-    The timestep, in code units, for the current step. For cosmology
-    the units are in free-fall times at the initial epoch (see :ref:`EnzoOutputFormats`). Default: generally 0, depending on problem
-Simulation Identifiers and UUIDs
-These parameters help to track, identify and group datasets. For reference,
-`Universally Unique Identifiers
-<>`_ (UUIDs) are
-opaque identifiers using random 128-bit numbers, with an extremely low chance
-of collision. (See :ref:`SimulationNamesAndIdentifiers` for a longer
-description of these parameters.)
-``MetaDataIdentifier`` (external)
-    This is a character string without spaces (specifically, something
-    that can be picked by "%s"), that can be defined in a parameter
-    file, and will be written out in every following output, if it is
-    found.
-``MetaDataSimulationUUID`` (internal)
-    A UUID that will be written out in all of the following outputs.
-    Like ``MetaDataIdentifier``, an existing UUID will be kept, but if one
-    is not found, and new one will be generated.
-``MetaDataDatasetUUID`` (internal)
-    A UUID created for each specific output.
-``MetaDataRestartDatasetUUID`` (internal)
-    If a ``MetaDataDatasetUUID`` UUID is found when the parameter file is
-    read in, it will written to the following datasets. This is used to
-    track simulations across restarts and parameter adjustments.
-``MetaDataInitialConditionsUUID`` (internal)
-    This is similar to ``MetaDataRestartDatasetUUID``, except it's used to
-    track which initial conditions were used.
-I/O Parameters
-There are three ways to specify the frequency of outputs:
-time-based, cycle-based (a cycle is a top-grid timestep), and, for
-cosmology simulations, redshift-based. There is also a shortened
-output format intended for visualization (movie format). Please
-have a look at :ref:`controlling_data_output` for more information.
-``dtDataDump`` (external)
-    The time interval, in code units, between time-based outputs. A
-    value of 0 turns off the time-based outputs. Default: 0
-``CycleSkipDataDump`` (external)
-    The number of cycles (top grid timesteps) between cycle-based
-    outputs. Zero turns off the cycle-based outputs. Default: 0
-``DataDumpName`` (external)
-    The base file name used for both time and cycle based outputs.
-    Default: data
-``RedshiftDumpName`` (external)
-    The base file name used for redshift-based outputs (this can be
-    overridden by the ``CosmologyOutputRedshiftName`` parameter). Normally
-    a four digit identification number is appended to the end of this
-    name, starting from 0000 and incrementing by one for every output.
-    This can be over-ridden by including four consecutive R's in the
-    name (e.g. RedshiftRRRR) in which case the an identification number
-    will not be appended but the four R's will be converted to a
-    redshift with an implied decimal point in the middle (i.e. z=1.24
-    becomes 0124). Default: RedshiftOutput
-``CosmologyOutputRedshift[NNNN]`` (external)
-    The time and cycle-based outputs occur regularly at constant
-    intervals, but the redshift outputs are specified individually.
-    This is done by the use of this statement, which sets the output
-    redshift for a specific identification number (this integer is
-    between 0000 and 9999 and is used in forming the name). So the
-    statement ``CosmologyOutputRedshift[1] = 4.0`` will cause an output to
-    be written out at z=4 with the name RedshiftOutput0001 (unless the
-    base name is changed either with the previous parameter or the next
-    one). This parameter can be repeated with different values for the
-    number (NNNN) Default: none
-``CosmologyOutputRedshiftName[NNNN]`` (external)
-    This parameter overrides the parameter ``RedshiftOutputName`` for this
-    (only only this) redshift output. Can be used repeatedly in the
-    same manner as the previous parameter. Default: none
-``OutputFirstTimeAtLevel`` (external)
-    This forces Enzo to output when a given level is reached, and at
-    every level thereafter. Default is 0 (off). User can usefully
-    specify anything up to the maximum number of levels in a given
-    simulation.
-    If this parameter is set to 1, whenever the finest level has finished
-    evolving Enzo will check for new signal files to output.  (See
-    :ref:`force_output_now`.)  Default 1.
-``XrayLowerCutoffkeV``, ``XrayUpperCutoffkeV``, ``XrayTableFileName`` (external)
-    These parameters are used in 2D projections (``enzo -p ...``). The
-    first two specify the X-ray band (observed at z=0) to be used, and
-    the last gives the name of an ascii file that contains the X-ray
-    spectral information. A gzipped version of this file good for
-    bands within the 0.1 - 20 keV range is provided in the
-    distribution in ``input/``. If these
-    parameters are specified, then the second field is replaced with
-    integrated emissivity along the line of sight in units of 10\
-    :sup:`-23` erg/cm\ :sup:`2`/s. Default: ``XrayLowerCutoffkeV =
-    0.5``, ``XrayUpperCutoffkeV = 2.5``.
-``ExtractFieldsOnly`` (external)
-    Used for extractions (enzo -x ...) when only field data are needed
-    instead of field + particle data. Default is 1 (TRUE).
-    Reserved for future use.
-    Reserved for future use.
-    Reserved for future use.
-    Reserved for future use.
-    Reserved for future use.
-    Reserved for future use.
-``ParallelRootGridIO`` (external)
-    Normally for the mpi version, the root grid is read into the root
-    processor and then partitioned to separate processors using communication.
-    However, for
-    very large root grids (e.g. 512\ :sup:`3`\ ), the root processor
-    may not have enough memory. If this toggle switch is set on (i.e.
-    to the value 1), then each processor reads its own section of the
-    root grid. More I/O is required (to split up the grids and
-    particles), but it is more balanced in terms of memory.
-    ``ParallelRootGridIO`` and ``ParallelParticleIO`` MUST be set to 1 (TRUE)
-    for runs involving > 64 cpus! Default: 0 (FALSE). See also ``Unigrid``
-    below.
-``Unigrid`` (external)
-    This parameter should be set to 1 (TRUE) for large cases--AMR as
-    well as non-AMR--where the root grid is 512\ :sup:`3`\  or larger.
-    This prevents initialization under subgrids at start up, which is
-    unnecessary in cases with simple non-nested initial conditions.
-    Unigrid must be set to 0 (FALSE) for cases with nested initial
-    conditions. Default: 0 (FALSE). See also ``ParallelRootGridIO`` above.
-``UnigridTranspose`` (external)
-    This parameter governs the fast FFT bookkeeping for Unigrid runs.
-    Does not work with isolated gravity. Default: 0 (FALSE). See also
-    ``Unigrid`` above.
-``OutputTemperature`` (external)
-    Set to 1 if you want to output a temperature field in the datasets.
-    Always 1 for cosmology simulations. Default: 0.
-``OutputCoolingTime`` (external)
-    Set to 1 if you want to output the cooling time in the datasets.
-    Default: 0.
-``OutputSmoothedDarkMatter`` (external)
-    Set to 1 if you want to output a dark matter density field,
-    smoothed by an SPH kernel. Set to 2 to also output smoothed dark
-    matter velocities and velocity dispersion. Set to 0 to turn off.
-    Default: 0.
-``OutputGriddedStarParticle`` (external)
-    Set to 1 or 2 to write out star particle data gridded onto mesh.
-    This will be useful e.g. if you have lots of star particles in a
-    galactic scale simulation. 1 will output just
-    ``star_particle_density``; and 2 will dump
-    ``actively_forming_stellar_mass_density``, ``SFR_density``, etc.
-    Default: 0.
-``VelAnyl`` (external)
-    Set to 1 if you want to output the divergence and vorticity of
-    velocity. Works in 2D and 3D.
-``BAnyl`` (external)
-    Set to 1 if you want to output the divergence and vorticity of
-    ``Bfield``. Works in 2D and 3D.
-``SmoothedDarkMatterNeighbors`` (external)
-    Number of nearest neighbors to smooth dark matter quantities over.
-    Default: 32.
-.. _streaming_param:
-Streaming Data Format
-``NewMovieLeftEdge``, ``NewMovieRightEdge`` (external)
-    These two parameters control the region for which the streaming
-    data are written. Default: ``DomainLeftEdge`` and ``DomainRightEdge``.
-``MovieSkipTimestep`` (external)
-    Controls how many timesteps on a level are skipped between outputs
-    in the streaming data. Streaming format is off if this equals
-    ``INT_UNDEFINED``. Default: ``INT_UNDEFINED``
-``Movie3DVolume`` (external)
-    Set to 1 to write streaming data as 3-D arrays. This should always
-    be set to 1 if using the streaming format. A previous version had
-    2D maximum intensity projections, which now defunct. Default: 0.
-``MovieVertexCentered`` (external)
-    Set to 1 to write the streaming data interpolated to vertices. Set
-    to 0 for cell-centered data. Default: 0.
-``NewMovieDumpNumber`` (internal)
-    Counter for streaming data files. This should equal the cycle
-    number.
-``MovieTimestepCounter`` (internal)
-    Timestep counter for the streaming data files.
-``MovieDataField`` (external)
-    A maximum of 6 data fields can be written in the streaming format.
-    The data fields are specified by the array element of
-    BaryonField, i.e. 0 = Density, 7 = HII
-    Density. For writing temperature, a special value of 1000 is used.
-    This should be improved to be more transparent in which fields will
-    be written. Any element that equals ``INT_UNDEFINED`` indicates no
-    field will be written. Default: ``INT_UNDEFINED`` x 6
-``NewMovieParticleOn`` (external)
-    Set to 1 to write all particles in the grids. Set to 2 to write
-    ONLY particles that aren't dark matter, e.g. stars. Set to 3/4 to
-    write ONLY particles that aren't dark matter into a file separate
-    from the grid info. (For example, ``MoviePackParticle_P000.hdf5``,
-    etc. will be the file name; this will be very helpful in speeding
-    up the access to the star particle data, especially for the
-    visualization or for the star particle. See ``AMRH5writer.C``) Set to 0
-    for no particle output. Default: 0.
-Hierarchy Control Parameters
-``StaticHierarchy`` (external)
-    A flag which indicates if the hierarchy is static (1) or dynamic
-    (0). In other words, a value of 1 takes the A out of AMR. Default:
-    1
-``RefineBy`` (external)
-    This is the refinement factor between a grid and its subgrid. For
-    cosmology simulations, we have found a ratio of 2 to be most useful.
-    Default: 4
-``MaximumRefinementLevel`` (external)
-    This is the lowest (most refined) depth that the code will produce.
-    It is zero based, so the total number of levels (including the root
-    grid) is one more than this value. Default: 2
-``CellFlaggingMethod`` (external)
-    The method(s) used to specify when a cell should be refined. This
-    is a list of integers, up to 9, as described by the following
-    table. The methods combine in an "OR" fashion: if any of them
-    indicate that a cell should be refined, then it is flagged. For
-    cosmology simulations, methods 2 and 4 are probably most useful.
-    Note that some methods have additional parameters which are
-    described below. Default: 1
-    :: 
-       1 - refine by slope		       6  - refine by Jeans length
-       2 - refine by baryon mass	       7  - refine if (cooling time < cell width/sound speed)
-       3 - refine by shocks 		       11 - refine by resistive length
-       4 - refine by particle mass	       12 - refine by defined region "MustRefineRegion"
-       5 - refine by baryon overdensity	       13 - refine by metallicity
-       	  (currently disabled)
-       101 - avoid refinement in regions
-             defined in "AvoidRefineRegion"
-``RefineRegionLeftEdge``, ``RefineRegionRightEdge`` (external)
-    These two parameters control the region in which refinement is
-    permitted. Each is a vector of floats (of length given by the
-    problem rank) and they specify the two corners of a volume.
-    Default: set equal to ``DomainLeftEdge`` and ``DomainRightEdge``.
-``RefineRegionAutoAdjust`` (external)
-    This is useful for multiresolution simulations with particles in
-    which the particles have varying mass. Set to 1 to automatically
-    adjust the refine region at root grid timesteps to only contain
-    high-resolution particles. This makes sure that the fine regions do
-    not contain more massive particles which may lead to small
-    particles orbiting them or other undesired outcomes. Setting to any
-    integer (for example, 3) will make AdjustRefineRegion to work at
-    (RefineRegionAutoAdjust-1)th level timesteps because sometimes the
-    heavy particles are coming into the fine regions too fast that you
-    need more frequent protection. Default: 0.
-``RefineRegionTimeType`` (external)
-    If set, this controls how the first column of a refinement region
-    evolution file (see below) is interpreted, 0 for code time, 1 for
-    redshift. Default: -1, which is equivalent to 'off'.
-``RefineRegionFile`` (external)
-    The name of a text file containing the corners of the time-evolving
-    refinement region. The lines in the file change the values of
-    ``RefineRegionLeft/RightEdge`` during the course of the simulation, and
-    the lines are ordered in the file from early times to late times.
-    The first column of data is the time index (in code units or
-    redshift, see the parameter above) for the next six columns, which
-    are the values of ``RefineRegionLeft/RightEdge``. For example, this
-    might be two lines from the text file when time is indexed by
-    redshift:
-    ::
-        0.60 0.530 0.612 0.185 0.591 0.667 0.208
-        0.55 0.520 0.607 0.181 0.584 0.653 0.201
-    In this case, the refinement region stays at the z=0.60 value
-    until z=0.55, when the box moves slightly closer to the (0,0,0)
-    corner. There is a maximum of 300 lines in the file and there is no
-    comment header line. Default: None.
-``MinimumOverDensityForRefinement`` (external)
-    These float values (up to 9) are used if the
-    ``CellFlaggingMethod`` is 2, 4 or 5. For method 2 and 4, the value is the density (baryon or particle), in code units, above which refinement occurs. When using method 5, it becomes rho [code] - 1. The elements in this array must match those in ``CellFlaggingMethod``. Therefore, if ``CellFlaggingMethod`` = 1 4 9 10, ``MinimumOverDensityForRefinement`` = 0 8.0 0 0.
-    In practice, this value is converted into a mass by
-    multiplying it by the volume of the top grid cell. The result is
-    then stored in the next parameter (unless that is set directly in
-    which case this parameter is ignored), and this defines the mass
-    resolution of the simulation. Note that the volume is of a top grid
-    cell, so if you are doing a multi-grid initialization, you must
-    divide this number by r\ :sup:`(d\*l)`\  where r is the refinement
-    factor, d is the dimensionality and l is the (zero-based) lowest
-    level. For example, for a two grid cosmology setup where a cell should be
-    refined whenever the mass exceeds 4 times the mean density of the
-    subgrid, this value should be 4 / (2\ :sup:`(3\*1)`\ ) = 4 / 8 =
-    0.5. Keep in mind that this parameter has no effect if it is
-    changed in a restart output; if you want to change the refinement
-    mid-run you will have to modify the next parameter. Up to 9
-    numbers may be specified here, each corresponding to the respective
-    ``CellFlaggingMethod``. Default: 1.5
-``MinimumMassForRefinement`` (internal)
-    This float is usually set by the parameter above and so is labeled
-    internal, but it can be set by hand. For non-cosmological simulations, it can be the easier refinement criteria to specify. It is the mass above
-    which a refinement occurs if the ``CellFlaggingMethod`` is
-    appropriately set. For cosmological simulations, it is specified in units such
-    that the entire mass in the computational volume is 1.0, otherwise it is in code units. There are 9 numbers here again, as per the
-    above parameter. Default: none
-``MinimumMassForRefinementLevelExponent`` (external).
-    This parameter modifies the behaviour of the above parameter. As it
-    stands, the refinement based on the ``MinimumMassForRefinement``
-    (hereafter Mmin) parameter is complete Lagrangian. However, this
-    can be modified. The actual mass used is
-    Mmin\*r\ :sup:`(l\*alpha)`\  where r is the refinement factor, l is
-    the level and alpha is the value of this parameter
-    (``MinimumMassForRefinementLevelExponent``). Therefore a negative value
-    makes the refinement super-Lagrangian, while positive values are
-    sub-Lagrangian. There are up to 9 values specified here, as per
-    the above two parameters. Default: 0.0
-``SlopeFlaggingFields[#]`` (external)
-    If ``CellFlaggingMethod`` is 1, and you only want to refine on the
-    slopes of certain fields then you can enter the number IDs of the
-    fields. Default: Refine on slopes of all fields.
-``MinimumSlopeForRefinement`` (external)
-    If ``CellFlaggingMethod`` is 1, then local gradients are used as the
-    refinement criteria. All variables are examined and the relative
-    slope is computed: abs(q(i+1)-q(i-1))/q(i). Where this value
-    exceeds this parameter, the cell is marked for refinement. This
-    causes problems if q(i) is near zero. This is a single integer (as
-    opposed to the list of five for the above parameters). Entering
-    multiple numbers here correspond to the fields listed in
-    ``SlopeFlaggingFields``. Default: 0.3
-``MinimumPressureJumpForRefinement`` (external)
-    If refinement is done by shocks, then this is the minimum
-    (relative) pressure jump in one-dimension to qualify for a shock.
-    The definition is rather standard (see Colella and Woodward's PPM
-    paper for example) Default: 0.33
-``MinimumEnergyRatioForRefinement`` (external)
-    For the dual energy formalism, and cell flagging by
-    shock-detection, this is an extra filter which removes weak shocks
-    (or noise in the dual energy fields) from triggering the shock
-    detection. Default: 0.1
-``MetallicityRefinementMinLevel`` (external)
-    Sets the minimum level (maximum cell size) to which a cell enriched
-    with metal above a level set by ``MetallicityRefinementMinMetallicity``
-    will be refined. This can be set to any level up to and including
-    ``MaximumRefinementLevel``. (No default setting)
-``MetallicityRefinementMinMetallicity`` (external)
-    This is the threshold metallicity (in units of solar metallicity)
-    above which cells must be refined to a minimum level of
-    ``MetallicityRefinementMinLevel``. Default: 1.0e-5
-``MustRefineRegionMinRefinementLevel`` (external)
-    Minimum level to which the rectangular solid volume defined by
-    ``MustRefineRegionLeftEdge`` and ``MustRefineRegionRightEdge`` will be
-    refined to at all times. (No default setting)
-``MustRefineRegionLeftEdge`` (external)
-    Bottom-left corner of refinement region. Must be within the overall
-    refinement region. Default: 0.0 0.0 0.0
-``MustRefineRegionRightEdge`` (external)
-    Top-right corner of refinement region. Must be within the overall
-    refinement region. Default: 1.0 1.0 1.0
-``MustRefineParticlesRefineToLevel`` (external)
-    The maximum level on which ``MustRefineParticles`` are required to
-    refine to. Currently sink particles and MBH particles are required
-    to be sitting at this level at all times. Default: 0
-``MustRefineParticlesRefineToLevelAutoAdjust`` (external)
-    The parameter above might not be handy in cosmological simulations
-    if you want your ``MustRefineParticles`` to be refined to a certain
-    physical length, not to a level whose cell size keeps changing.
-    This parameter (positive integer in pc) allows you to do just that.
-    For example, if you set ``MustRefineParticlesRefineToLevelAutoAdjust``
-    = 128 (pc), then the code will automatically calculate
-    ``MustRefineParticlesRefineToLevel`` using the boxsize and redshift
-    information. Default: 0 (FALSE)
-``FluxCorrection`` (external)
-    This flag indicates if the flux fix-up step should be carried out
-    around the boundaries of the sub-grid to preserve conservation (1 -
-    on, 0 - off). Strictly speaking this should always be used, but we
-    have found it to lead to a less accurate solution for cosmological
-    simulations because of the relatively sharp density gradients
-    involved. However, it does appear to be important when radiative
-    cooling is turned on and very dense structures are created.
-    It does work with the ZEUS
-    hydro method, but since velocity is face-centered, momentum flux is
-    not corrected. Species quantities are not flux corrected directly
-    but are modified to keep the fraction constant based on the density
-    change. Default: 1
-``InterpolationMethod`` (external)
-    There should be a whole section devoted to the interpolation
-    method, which is used to generate new sub-grids and to fill in the
-    boundary zones of old sub-grids, but a brief summary must suffice.
-    The possible values of this integer flag are shown in the table
-    below. The names specify (in at least a rough sense) the order of
-    the leading error term for a spatial Taylor expansion, as well as a
-    letter for possible variants within that order. The basic problem
-    is that you would like your interpolation method to be:
-    multi-dimensional, accurate, monotonic and conservative. There
-    doesn't appear to be much literature on this, so I've had to
-    experiment. The first one (ThirdOrderA) is time-consuming and
-    probably not all that accurate. The second one (SecondOrderA) is
-    the workhorse: it's only problem is that it is not always
-    symmetric. The next one (SecondOrderB) is a failed experiment, and
-    SecondOrderC is not conservative. FirstOrderA is everything except
-    for accurate. If HydroMethod = 2 (ZEUS), this flag is ignored, and
-    the code automatically uses SecondOrderC for velocities and
-    FirstOrderA for cell-centered quantities. Default: 1
-    ::
-              0 - ThirdOrderA     3 - SecondOrderC
-              1 - SecondOrderA    4 - FirstOrderA
-              2 - SecondOrderB  
-``ConservativeInterpolation`` (external)
-    This flag (1 - on, 0 - off) indicates if the interpolation should
-    be done in the conserved quantities (e.g. momentum rather than
-    velocity). Ideally, this should be done, but it can cause problems
-    when strong density gradients occur. This must(!) be set off for
-    ZEUS hydro (the code does it automatically). Default: 1
-``MinimumEfficiency`` (external)
-    When new grids are created during the rebuilding process, each grid
-    is split up by a recursive bisection process that continues until a
-    subgrid is either of a minimum size or has an efficiency higher
-    than this value. The efficiency is the ratio of flagged zones
-    (those requiring refinement) to the total number of zones in the
-    grid. This is a number between 0 and 1 and should probably by
-    around 0.4 for standard three-dimensional runs. Default: 0.2
-``NumberOfBufferZones`` (external)
-    Each flagged cell, during the regridding process, is surrounded by
-    a number of zones to prevent the phenomenon of interest from
-    leaving the refined region before the next regrid. This integer
-    parameter controls the number required, which should almost always
-    be one. Default: 1
-``RefineByJeansLengthSafetyFactor`` (external)
-    If the Jeans length refinement criterion (see ``CellFlaggingMethod``)
-    is being used, then this parameter specifies the number of cells
-    which must cover one Jeans length. Default: 4
-``JeansRefinementColdTemperature`` (external)
-    If the Jeans length refinement criterion (see ``CellFlaggingMethod``)
-    is being used, and this parameter is greater than zero, it will be
-    used in place of the temperature in all cells. Default: -1.0
-``StaticRefineRegionLevel[#]`` (external)
-    This parameter is used to specify regions of the problem that are
-    to be statically refined, regardless of other parameters. This is mostly
-    used as an internal mechanism to keep the initial grid hierarchy in
-    place, but can be specified by the user. Up to 20 static regions
-    may be defined (this number set in ``macros_and_parameters.h``), and
-    each static region is labeled starting from zero. For each static
-    refined region, two pieces of information are required: (1) the
-    region (see the next two parameters), and (2) the level at which
-    the refinement is to occurs (0 implies a level 1 region will always
-    exist). Default: none
-``StaticRefineRegionLeftEdge[#]``, ``StaticRefineRegionRightEdge[#]`` (external)
-    These two parameters specify the two corners of a statically
-    refined region (see the previous parameter). Default: none
-``AvoidRefineRegionLevel[#]`` (external)
-    This parameter is used to limit the refinement to this level in a
-    rectangular region.  Up to MAX_STATIC_REGIONS regions can be used.
-``AvoidRefineRegionLeftEdge[#]``, ``AvoidRefineRegionRightEdge[#]`` (external) 
-    These two parameters specify the two corners of a region that
-    limits refinement to a certain level (see the previous
-    parameter). Default: none
-``RefineByResistiveLength`` (external)
-    Resistive length is defined as the curl of the magnetic field over
-    the magnitude of the magnetic field. We make sure this length is
-    covered by this number of cells. Default: 2
-``LoadBalancing`` (external)
-    Set to 0 to keep child grids on the same processor as their
-    parents. Set to 1 to balance the work on one level over all
-    processors. Set to 2 or 3 to load balance the grids but keep them
-    on the same node. Option 2 assumes grouped scheduling, i.e. proc #
-    = (01234567) reside on node (00112233) if there are 4 nodes. Option
-    3 assumes round-robin scheduling (proc = (01234567) -> node =
-    (01230123)). Set to 4 for load balancing along a Hilbert
-    space-filling curve on each level. Default: 1
-``LoadBalancingCycleSkip`` (external)
-    This sets how many cycles pass before we load balance the root
-    grids. Only works with LoadBalancing set to 2 or 3. NOT RECOMMENDED
-    for nested grid calculations. Default: 10
-Hydrodynamic Parameters
-``UseHydro`` (external)
-    This flag (1 - on, 0 - off) controls whether a hydro solver is used.  
-    Default: 1
-``HydroMethod`` (external)
-    This integer specifies the hydrodynamics method that will be used.
