[Libmesh-users] Good Exodus News

[Derek G. <fri...@gm...>]

No... I still haven't fixed the writer so that it doesn't blow up when  
trying to write a block 0.... but I do have good Exodus related news:  
The full SEACAS set of tools has been open sourced: http://sourceforge.net/projects/seacas/

This includes nem_slice and nem_spread which can take a serial  
ExodusII file and decompose it for parallel reading by a parallel  
Nemesis reader (which libMesh supports) and put parallel Nemesis files  
back together to create a serial Exodus file (for visualization, etc).

Also... SEACAS includes exodiff... which can show you the difference  
between solutions stored in two different Exodus files.  It somewhat  
overlaps with meshtool... but does have it's uses.  For instance, we  
use it for regression tests because it can tell you when your solution  
changes within some tolerance (so that changing machines architectures  
or operating systems won't cause false positives).

Anyway... if you use ExodusII i/o with libMesh you should probably  
check out SEACAS... it's a pretty useful set of tools.
