CitcomS

CitcomS is a finite element code designed to solve compressible thermochemical convection problems relevant to Earth's mantle.

Written in C, the code runs on a variety of parallel processing computers, including shared and distributed memory platforms.

CitcomS-3.0.3.tar.gz [2008-09-08]: This release fixes five bugs that are related to regional coordinate refinement, geoid, full-regional coupling, and the geoid post-processing script.
This release (v3.0) features two implementations of compressible convection; the ability to resume computation from previous checkpoints; multi-component chemical convection; a fixed non-Newtonian solver; a rheology option for pseudo-plasiticity; composition dependent viscosity and heat generation; compressed ASCII output; an easier way for mesh refinement for the radial coordinate; an exchanger package for solver coupling; an option to disable monitoring of maximum temperature, and other new features.
CitcomS-cookbook8-restart.tar.gz: Checkpoint at the 9,000th time step which allows user to shorten the computation time (if the solver is interrupted before finishing the computation, one can resume the computation from the checkpointed state). NOTE: The checkpoint files are produced by an x86 machine and may not be usable by other types of machines, e.g., PowerPC.

If you are interested in following the main line of development, use the following Subversion command:
