[CIG-SHORT] general mesh optimization

[Rebecca Bendick]

Hi, there.  I've successfully run all the 3d examples provided in the  
PyLith distribution, and I'm on to building my own problems, but  
without success.  I took the advice offered in the <embedded fault>  
thread and, rather than use a complicated input from LaGRIT, tried to  
modify the mesh from the tet4 example for a thrust problem.  I can  
build meshes that look fine, but they don't seem to meet the  
requirements of PyLith.  I've gotten a few different errors,  
especially ALE:Exception and the one below.  Is there some way to  
force LaGRIT or whatever mesher is being used to output a mesh that  
will work in PyLith?  Or, is there a thrust-fault example that I could  
use as a template to prevent geometry problems?

Thanks,
Becks
