Inquiry about rotational control (RX, RY, RZ) in flex3d.mph

Hello,

I'm new to COMSOL and was very excited to find your open-source project. Thank you for sharing your work!

I'm trying to implement rotational constraints (RX, RY, RZ) in the comsol/flex3d.mph model, but I'm running into some trouble. The model currently only seems to have controls for translational movement (UX, UY, UZ).

I attempted to add the rotational degrees of freedom (e.g., RX) myself, but my changes either resulted in errors or did not produce the expected behavior.

Could you please provide some guidance on the correct way to set up these rotational constraints? Is there a specific method I should be using?

Alternatively, I was wondering if the current file is an intermediate version. Do you have a version of the model that already includes rotational controls?

Any help you could offer would be greatly appreciated. Thank you!

The request points to comsol/flex3d.mph and its existing UX, UY, and UZ controls. Start by inspecting that model and the current constraint setup; done means a documented COMSOL approach or model version with RX, RY, and RZ controls that behaves as expected.
