Hi, I don't expect to get very far with this issue, because I seem to have an extremely buggy version of SW.

When I try to use an adaptive solver, I get the message "One or more components have no material defined". This message comes up three times.

I know that the materials are defined because it solves perfectly using a standard non-adaptive solver.

I either get the above message or it crashes. Only certain models are causing the issue.

It's obviously not a major issue, just annoying as I can't go a day without SW crashing.

Any clues as to why the adaptive solver might not accept certain models?

Thanks
