** ERROR 200170 ** One or more unconnected cavities are overconstrained. Check the constraints on the model and run the analysis again.
The model consists of two or more cavities. Warp/Stress analysis requires that suitable constraints be applied to each individual cavity to prevent rigid-body movement in response to the applied loads. The solver has determined that one or more cavities is overconstrained.
Check the constraints that you have applied to each cavity in the model.
