[CIG-SHORT] problem about discreting 3-D mesh model

[Brad Aagaard]

Tu,

You could be running into a mesh generation issue or running out of 
memory. If you can generate the mesh at a coarser resolution, then I 
suspect you may be running out of memory.

You can generate the mesh at a coarser resolution and use uniform global 
refinement within PyLith to get the desired resolution. See 
examples/3d/tet4 Steps 2 and 4 for how to use uniform global refinement.

Regards,
Brad
