Latest Release (3.1.1)

CitcomS-3.1.1.tar.gz [2009-07-31]

This release of CitcomS 3.1 adds the ability to convert temperature and composition to seismic velocities. The seismic velocities output can be uploaded to CIG seismic portal for SPECFEM3D simulation to generate synthetic seismograms. Other enhancements in bug-fix version 3.1.1 include: Allowing tracers in global model with nproc > 2; Simplified convergence control for Stokes solver; The norms of div(u), u, and p are no longer dependent on the grid size; Adding self-gravitational effect on geoid and adding Consistent-Boundary-Flux (CBF) method to compute dynamic topography; Adding GMT/NetCDF grd input for surface velocity boundary conditions, initial temperature, material dependence and local Rayleigh number in surface layers; Adding capability to read in time- and geographic-dependent, top surface temperature boundary conditions; Allowing multi-component chemical viscosity; Optimizing the speed (Cookbook 8 becomes 13% faster than v3.0); Better convergence for the coupled solver case; Several bugs are fixed. 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.

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.
