Dear All,

I want to make electrical simulation combine with thermal (heat transfer) aspect on complex assembly.

I've made the FE model with hypermesh optistruct profile and export as .fem file, but I can not import it to FLUX.

Is there any way to do it?

Please, need your advise.

Thank you,

Best regards,

I've managed this error as well.

Try this: export model to .fem file in OptiStruct profile, then switch to Nastran and export to .bdf, copy all CPYRA elements in notepad from .fem, paste them before CHEXA in .bdf file, save and then import Nastran file in FLUX.

If somebody knows shorter way to run it, I'll be thankful.

Remember to keep 1st order elements in Hypermesh and assign to each component (or rather volume) another property.

As said Pioborzy, you have to use the Nastran NX user profile for instance so that you have all kinds of elements (penta, hexa, tetra, pyra). Then in Element types, update all elements and export again in Nastran Format.

Make sure to have one property assigned to each separate volume you want in Flux.
