+ For some test problems (mostly in hydro_rk), the relevant parameters could be defined in physical CGS units. Default: 0
+ Minimum value for density in hydro_rk/EvolveLevel_RK.C. Default: 1e-30 (note that the default value assumes UsePhysicalUnit = 1)
+ Minimum value for temperature in hydro_rk/EvolveLevel_RK.C. Default: 1e-10 (note that the default value assumes UsePhysicalUnit = 1)
+ Flux limiter in the minmod Van Leer formulation. Must be between 1 (most dissipative) and 2 (least dissipative). Default: 1.5
+ Coordinate systems to be used in hydro_rk/EvolveLevel_RK.C. Currently implemented are Cartesian and Spherical for HD_RK, and Cartesian and Cylindrical for MHD_RK. See Grid_(MHD)SourceTerms.C. Default: Cartesian
+ Types of Equation of State used in hydro_rk/EvolveLevel_RK.C (0 - ideal gas, 1 - polytropic EOS, 2 - another polytropic EOS, 3 - isothermal, 4 - pseudo cooling, 5 - another pseudo cooling, 6 - minimum pressure); see hydro_rk/EOS.h. Default: 0
+ From C_h (the Dedner wave speeds at which the div*B error is isotropically transferred; as defined in e.g. Matsumoto, PASJ, 2007, 59, 905) and this parameter, C_p (the decay rate of the wave) is calculated; see ComputeDednerWaveSpeeds.C Default: 1.0
+ Set to 1 to use the CUDA-accelerated (M)HD solver. Only works if compiled with cuda-yes. Default: 0
- Select direction of shearing boundary. Default is x direction. Changing this is probably not a good idea.
the units are in free-fall times at the initial epoch (see :ref:`EnzoOutputFormats`). Default: generally 0, depending on problem
+ Select direction of shearing boundary. Default is x direction. Changing this is probably not a good idea.
+ While this parameter was initially designed to describe the kick by cosmic strings in CosmologySimulation, it can be used to model the velocity (in km/s) that the baryons should move relative to dark matter at the initial redshift, in order to study the effect discussed by Tseliakhovich & Hirata (astro-ph:1005.2416). Default: 0
+ The time interval, in code units, between time-based tracer particle outputs (defined in ComputeRandomForcingNormalization.C). A
+ This parameter is used to set the velocities of the tracer particles equal to the gas velocities in the current cells. Tracer particles are massless and can be used to output values of the gas as they advect with the fluid. Default: 0
+ Rays will be emitted within this angle in degrees of the poles from sources with "Beamed" types. Default: 30
+ Adaptive ray tracing timesteps will be restricted by a maximum change of 10% in neutral fraction if this parameter is set to 1. If set to 2, then the incident flux can change by a maximum of 0.5 between cells. See Wise & Abel (2011) in Sections 3.4.1 and 3.4.4 for more details. Default: 0
+ Must be 1 when RadiativeTransferHIIRestrictedTimestep is non-zero. When RadiativeTransferHIIRestrictedTimestep is 0, then the radiative transfer timestep is set to the timestep of the finest AMR level. Default: 0
+ When turned on, the grids are load balanced based on the number of ray segments traced. The grids are moved to different processors only for the radiative transfer solver. Default: 0
For details on each of the different star formation methods available in Enzo see :ref:`star_particles`.
+The parameters below are considered in sink creation routines: sink_maker, star_maker8, star_maker9.
+ While this parameter is used to determine the accretion kernel in star_maker8.C, there is no choice other than 1 at the moment: Ruffert, ApJ (1994) 427 342 (a typo in the parameter name...). Default: 0
+ This parameter is used to turn on sink particle creation by star_maker8.C and also its feedback. Currently implemented are: 1 - protostellar jets along the magnetic fields, 2 - protostellar jets along random directions, 3 - isotropic main sequence stellar wind, 4 - not implemented, 5 - not implemented, 6 - methods 2 and 3 combined. Default: 0
+ This parameter is used to decide whether mass increase reached the ejection threshold for StellarWindFeedback=1, 2, or 6 in star_maker8.C. Default: 0.1
+ This parameter is used to decide whether mass increase reached the ejection threshold for StellarWindFeedback = 3 or 6 in star_maker8.C. Default: 10.0
+ In star_maker.C, if the newly-created sink particle is within a certain distance from the closest pre-existing sink, then add to it rather than creating a new one.
