[MOAB-dev] Importing BC in moab directly from cubit mesh file

[Tim Tautges]

Hmm, good question.  TTYTT, I'm not familiar with how the BCs are stored in the .cub file, and I'm pretty sure that 
they're not parsed out right now.  The blocks, sidesets, and nodesets are parsed out.  The format they have in the MOAB 
database is described in the metadata_info document (in the doc subdirectory).  In brief, the entity set structure after 
reading a .cub file reflects the geometric topology inclusion structure as it was in cubit.  That is, the 
material/neumann/dirichlet sets in moab will contain geometric topology sets, which will contain the mesh owned by that 
geometric topology in the original cubit model.

If you'd be interested in improving the .cub reader, I could describe the process (basically, reverse engineering what's 
in the .cub file, using some of the classes in CGM that write the .cub file information).  It's not for the faint of 
heart, but isn't impossible either.  In moab, the reader class is named Tqdcfr for a reason (Tim's quick 'n dirty cub 
file reader).
