Supported suctural elements in FSI CalculiX OpenFOAM

Hi @Ulrich
I am trying to develop a general way to handle higher order elements in the CalculiX Adapter. My question is with respect to the following part of your answer:

I am trying to figure out if a general way of handling this can be implemented in the adapter code. The corresponding GitHub issue is this one. If you have more thoughts on this it would be of great help if you could comment on the issue.

Handling of higher order elements is a recurring problem and we are thinking of handling it in a general way.
