[MOAB-dev] mbconvert from abaqus to h5m

[Jacob Hochhalter]

Hi Iulian,

I would like to use the converter to translate an abaqus mesh 
representation to h5m.  I only am concerned with the mesh:  nodal 
coordinates, element connectivity, and the associated sets.  I am 
attaching a zip file which contains 6 small inp files that you could use 
for testing, which represent commonly used element topologies. 
Translation of the information under the following blocks would be 
sufficient (for me):  *Node, *Element,*Nset, *Elset.

I wrote out the inp files from the ABAQUS CAE. There is one option that 
I chose within ABAQUS that is useful. Inside the 'Model->Attributes' 
menu in ABAQUS, one can select a check box that says "Do not use parts 
and assemblies in input files" (as shown in the attached image).  Having 
"PART" and "ASSEMBLY" info in the .inp file complicates mesh translation 
since one would need to aggregate & assimilate the node and element 
numbering of all the possible parts & assemblies.  By making the 
selection shown in the attached image, ABAQUS will take care of all that 
before writing the .inp file, combining the various parts and assemblies 
into a single coherent mesh description.  I do not think there would be 
any loss of generality for MOAB in enforcing that this option be 
selected for .inp files that mbconvert uses, and it would certainly make 
the translation of abaqus meshes much simpler and robust.

Hope this helps!  Let me know if you have any other questions/thoughts.

- Jake
