Can Run Analysis But Not Optimization


I can run analysis, but not optimization.

The model might not be sufficiently constrained (some parts are free to move). Also, contacts between parts may not be detected properly.


To fix this, click Find Options on the Contact tool's guide bar, deselect Auto search distance, and enter a value. If the parts are separated, enter a larger value. But if the parts are touching, try a smaller value. You can also change from Surfaces to Parts on the guide bar to define contact pairs. Contact detection issues are often related to poor CAD data.
