Hypermesh and ABAQUS assemblies

I see this has been discussed before but without an obvious conclusion. ..Does Hypermesh support the export of *PART, *INSTANCE & *ASSEMBLY Abaqus keywords? From my research it seems not, although Hypmesh supports sub-structuring for other codes.

This leads me on to the question of whether anybody has managed to achieve this through a workaround or macro? My only options so far are to export each part manually and re-assemble by hand creating the sub-structured deck - owch! I've looked at bring my model deck into Abaqus CAE and re-arranging that way but doesn't seem much easier with the mess that is brought in.

Anyone with experience of this out there? Cheers!

At the time of this writing, we do not yet support ABAQUS instances, as they use duplicate IDs. Your process is probably the best workaround for the time being. We have a request for enhancement (RFE) in the works to add support for this, but it is not a high priority relative to other ABAQUS features we are adding for the next release.

Regarding input, there is a abaqus.env file parameter to 'flatten' the file for import, but for export, what you are doing is probably the best way.

I have the opposite problem. I have some legacy ABAQUS files (and files from subcontractors) written in the assembly format, that I wish to read into HyperMesh so that I can convert the models to LS-DYNA. I no longer have access to ABAQUS CAE so I can't create a flat input file. The only work around I can think of is to split the ABAQUS files into individual files for each part, then import each part into HM and offset the node/element numbers etc. This is OK for small models, but becomes very tedious for models with many parts. It would be very useful if HM could support reading ABAQUS assemblies.
