Abaqus Import Problem

Coreform Cubit Importing/Exporting
#1

Coreform Cubit 2021.5
Fedora Core 34

I have an alleged Abaqus mesh, which Cubit refuses to import, telling me

Reading Abaqus input file '/home/adavis/cube.inp'...
Processing 7887 lines in the file...

ERROR: No nodes found in the Abaqus input file
  '/home/adavis/cube.inp'. This input file was skipped.
Finished reading '/home/adavis/cube.inp'

But…

Is my Abaqus file bogus?

Hi,

Can you add the Abaqus file here? I will take a look at it.

cube.inp (206.3 KB)

NOTE: its not a JOU file, INP isnt recognised on your upload filter, rename to .inp

Admin Edit: Added support for .inp file uploads, and modified extension – GV

I had to put the part in an instance and read this as free mesh only. This fails creating mesh based geometry. I think it is because the there are degenerate elements.

I got some feedback from my in-house Abaqus expert and was told that you really should include an assembly and an instance that references the PART.

*ASSEMBLY, NAME=Assembly1
*INSTANCE, NAME=Region_1, PART=Region
*END INSTANCE
*END ASSEMBLY

I used draw element all to get a better visualization.

I’m not sure, but I’m guessing that your Abaqus file is not handling tet 10 elements correctly. I can read and write tet 10’s from Cubit.
