Hi
the principle remins the same for all physics: all dependent variables require minimum 1 or 2 BC to define the constants for the equation integrations. So go through all yourphysics, and all your dependent variables and chack that the BC sem coherent. The rest depends on your model and ho you assemble it.

Good luck

Hi
do an eigenfrequency study. If your beam is "pre-stressed" check how to do first a stationary stress case, then use that as linearisation point for the eigenfrequency solver. There is for certain physics a predefined "pre stressed eigenfrequency" solver possibility
