====== LithoMop ======

[[http://geodynamics.org/cig/software/lithomop|LithoMop Software Page]]

LithoMop is a finite element code for the solution of the visco-elastic/plastic deformation that was designed for lithospheric modeling problems.

===== LithoMop System Requirements =====

Lithomop3d should work on any UN*X system.  It requires the following
language tools:

  * A Fortran compiler.  Both older Fortran-77 and modern Fortran-9x compilers will work.
  * A C compiler.
  * A C++ compiler.
  * [[http://www.python.org/|Python 2.3 or later]]

If you are using a modern UN*X system, there is a good chance that all of the above tools are already installed.
  
In addition, Lithomop3d v0.7.2 requires the following software packages:

  * (Optional) An MPI library.  Lithomop3d itself is a serial code which does not use MPI.  However, both PETSc and Pythia (detailed below) require MPI by default.  A popular choice is [[http://www-unix.mcs.anl.gov/mpi/mpich|MPICH]].

MPICH is recommended by the PETSc installation instructions; in fact, PETSc's configure.py can automatically download and install MPICH for you ('--download-mpich=yes').

If you decide to skip installing MPI, you will have to specially configure both PETSc and Pythia not to use MPI.

  * [[http://www.mcs.anl.gov/petsc/|PETSc version 2.3]], available from the MCS web site at Argonne National Laboratory.

If you decide not to install MPI, give PETSc's configure.py the '--with-mpi=0' option.  See the PETSc installation instructions for details.

  * [[http://www.geodynamics.org/cig/software/packages/pythia|Pythia version 0.8]].  The easiest way to install Pythia is to download the GNU-style pythia-0.8.tar.gz source package from the CIG web site under 'Software -> Software Packages -> Pythia'

If you decide not to install MPI, give Pythia's configure the '--without-mpi' option.  General information about Pythia can be found at the [[http://www.cacr.caltech.edu/projects/pyre|Pyre project page]].

Note that releases of both PETSc and Pythia are generally not
backwards-compatible with prior versions.  Therefore, you must install
PETSc v2.3 and Pythia v0.8 specifically; future versions of PETSc and
Pythia would not be expected to work with Lithomop3d v0.7.2.
