FDS-SMV 6.4.0 Minor Release

A new minor release, FDS-SMV 6.4.0, has been posted.  This release fixes a couple of issues with the combustion model.  The first was a bug in the reaction divergence expression that led to below ambient temperatures in some instances.  The second was a problem with boundedness for multiple reactions, mainly affecting complex chemistry.

In this release we have also fixed several issues with MPI scaling.  With a time grant on the Oak Ridge National Lab supercomputer, Titan, we were able to run FDS on up to roughly 10,000 processes.  Linear scaling was achieved to roughly 16^3 mesh size (4096 cells/mesh).

For further details on this release see the FDS Release Notes.
