Enforced rotation
Enforced rotation
(OP)
I'm trying to model a frame (see image) with an applied torque, and a set rotational displacement.
The plate is fixed the upper right/lower left corners (UR LL) and the load is applied through a RBE2 at the center of the plate.
It works fine with torque only, but the solver crashes when I try to combine it with enforced rotation. Can the RBE2 not be used in this situation? And what would you recommend for applying this kind of load to simulate an enforced displacement? (The frame has a shaft attached to it that is subject to torque loads, and we want to verify that the frame is ok for some given misalignment (represented by the forced displacement angle).

RE: Enforced rotation
I can imagine solvers having trouble doing both (i.e. as simultaneous conditions), as the rotation created by the torque load is not the same as the imposed rotation, and the solver has to switch modes.
Why not just find out what the reaction torque is for the imposed rotation, and add that to the imposed torque load in a separate case?
RE: Enforced rotation
if this is what you're trying, run two load cases and combine them
