[MOAB-dev] mbconvert from abaqus to h5m

[Paul Wilson]

Hello Jacob,

Since I was the main author of this (nearly 6 years ago), I'll add some 
comments.

The use case I was working always had PARTs defined separately from 
ASSEMBLYs that were composed of INSTANCEs of those PARTs.  I hope it 
won't be hard to support your use case, which doesn't seem to use any of 
those constructs.

I was able to load it successfully without any changes to MOAB by adding 
PART and ASSEMBLY information, as in the attached file.

For future reference, it also only currently supports a subset of the 
element types and metadata.  It will definitely support the linear tets 
that are in your sample, but does not support many higher order elements.

Paul
