Dear all,
In my model I have a gravity load and a centriful force.
I would like to take into account inertia effects of the point mass due to the centrifugal force. With "Create Inertial load" one can add a velocity. However one cannot select an application region, inertial effects apply to the entire model. In my case I have a fixed bottom part and a rotating upper part. I can select a velocity for the upper parts however when I add also the pointmass I get this message during the run:
Patran 2017.0.3 has found nodes for which both SPCs and dependent MPC relationships exist. Nastran will not accept such a specification.
So I do not know how I can take into account the inertia of this point mass due to centrifugal forces. In this case it cannot be neglected and a centrifugal force for the complete model is not coorect (lower part is not rotating).
Thanks in advance.
