Acusolve post processing in Abaqus

Hello!

When I try to post-process the results of an Acusolve simulation, transferring the results to run in Abaqus other analysis, with acuOdb, at a certain moment it says: 'This model contains an element type that is not yet supported: UNDEFINED. The requested process requires that all element types in the model be supported'.

The Acusolve simulation is correct, so it makes me wonder if some element types of this solver are not compatible with Abaqus.

Any solution for this?

Thank you.

Are you able to attach the AcuSolve input (.inp) file used for this analysis?

Could you use the point data instead of an actual .odb file? (There are ways to write x/y/z/value files.)

It looks like 5-node pyramid elements are the problem here. It's likely when that script was written, pyramids were not supported in Abaqus - but it looks like they may be supported now.

If I can get a modified executable - would you need Windows or Linux? Which version of AcuSolve are you running?

Yes, it seems that 5-node pyramid elements are the problem. I'm running Acusolve 2021.2. Maybe in a later update it works?

Nothing has changed in later versions yet. We'll make the request to support writing the pyramids. In the meantime, if you create the mesh with all-tets (so tets in the BL instead of wedges/prisms) you won't have any pyramids, and it should translate OK.

Can you also specify with which company/university you work?

Can you provide more details on what you are trying to do - why you want to use acuOdb?

Might there be a different process to map the AcuSolve results to the Abaqus model - maybe in HyperWorks or SimLab if you're setting up the Abaqus model there? (Or - where are you setting up the Abaqus model? Will that accept the input of x/y/z location and data rather than the ODB file?)

If you can provide your company/university information, etc, we can perhaps push the development
