Attach Spring to a rigid element
I am looking for a way to save CPU time since my model got quite complex. Is there a way to tell radiOSS to calculate one or several parts as rigid?
I tried using the checkmark rbody for the relevant part but it caused a few errors.
A simplified model is attached. I'd like the upper one of the cuboids to behave like a rigid.
There seems to be a kind of hourglassing? happening as well, which I didn't manage to solve.
Advice on any part of this is appreciated!
