Abaqus mesh format

[jinlin.niu]

Hello all,

    Since MOOSE supports reading and writing a large number of formats, I try a Abaqus .inp format which is from a ICEM mesh. But MOOSE tells me "vtkExodusIIReaderPrivate (0x488d450): Unable to read database parameters

    My mesh file is "project3.inp" in attachment.

    So, I want to know the reason.

    Thank you!

The error message above doesn't make sense to me... I don't know why an ExodusII reader object would be getting invoked to read an Abaqus file.  This error is from Peacock I'm guessing?

That said, your Abaqus input file *should* work with MOOSE after some minor modifications:

Change:

"TYPE=S4" -> "TYPE=CPE4" 

and 

"TYPE=B31" -> "TYPE=T3D2"

everywhere they appear.

The S4 and B31 element types correspond to four-noded shell and two-noded beam elements, respectively, and are currently not supported by the Abaqus reader in libmesh. 

I don't see why we couldn't just treat them as the corresponding types when reading the file in, though, so I will probably patch the Abaqus reader to support this.
