DynEarthSol3D is a finite element code that solves the momentum balance and 
the heat transfer in Lagrangian form using unstructured meshes. It can be
used to study the long-term deformation of Earth's lithosphere and problems

This version of DES3D contains libadaptivity from Fluidity
a self-contained library for anisotropic adaptive mesh refinement, 
works well as a mesh optimizer for DES3D's remeshing.


* You will need a recent C++ compiler that supports C++11 standard. (GNU g++
  4.4 or newer version will suffice.)
* You will need a recent version of Boost::Program_options library (1.42 or
  newer version). Instructions for building the library:
  -- Download the source code from www.boost.org
  -- In the untarred source directory, run "./bootstrap.sh"
  -- In the same directory, run "./b2 --with-program_options -q" to build
     the library.
* You will need Python 2.6+ or 3.2+ and the Numpy package.

For libadaptiviy, you further need
* VTK5 (v5.8 and v5.10 tested) built from source or development packages.
* MPI (openmpi v1.4~v1.6, and mpich2 v1.4 tested).

* Edit 'Makefile', 
  1) Modify BOOST_ROOT_DIR if you manually built or installed 
  boost library. If you followed the instructions above to build 
  Boost::Program_options library, set BOOST_ROOT_DIR to the untarred boost
  2) If using libadaptivity:
    2.1) Set 'useadapt = 1' and 'ndims = 3'. libadaptivity works only for 3D.
    2.2) Set VTK_INCLUDE and VTK_LIBS paths if vtk is not in standard location.
    2.3) Set LIB_MPIFORTRAN for your mpi library
* Run "make" to build optimized executable.
* Or run "make opt=0" to build a debugging executable.
* Or run "make openmp=0" to build the executable without OpenMP. This is
  necessary to debug the code under valgrind.


* setenv LD_LIBRARY_PATH /home/student/dennist/TOOL/tbb44_20160316oss/build/linux_intel64_gcc_cc4.4.7_libc2.12_kernel2.6.32_release (for utig)
* setenv LD_LIBRARY_PATH /home/u1/xt577/Tool/tbb44_20160316oss/build/linux_intel64_gcc_cc4.4.7_libc2.12_kernel2.6.32_release (for jsg)
* Execute "dynearthsol2d inputfile".
* Several example input files are provided under 'examples/' directory. The
  format of the input file is described in 'examples/defaults.cfg'.
* Benchmark cases with analytical solution can be found under 'benchmarks/'
* Execute the executable with '-h' flag to see the available input parameters
  and their descriptions.


* Run "2vtk.py modelname" to convert the binary output to VTK files.
* Execute 2vtk.py with '-h' flag to see more usage information.
* Some of the simulation outputs might be disabled. Edit 2vtk.py and
  output.cxx to disable/enable them.
* Plot the VTK files with Paraview or LLNL's Visit program.
