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-3.2.0.tar.gz [2012-02-02]: This release of CitcomS 3.2 has numerous changes from 3.1.1. These include improved implementations of internal stress, radial layer dependent viscosity, and velocity boundary conditions. Improvements have also been made in solver convergence controls, VTK output and several bug fixes. Finally, the Pyre configuration option has been turned off by default, though it can be enabled during configuration. See the NEWS file in the package for more details.

This release is slightly backward incompatible with v3.0. See the History section in the manual for more details.
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.
