Gravity and Stress Stiffening

steverossi

I am trying to perform a 3D modal analysis of a plate (AL). I applied a gravitational load but "whats wrong" says "loads will be ignored unless stress stiffening is applied (see image). If I add stress stiffening and try to solve - solver keeps running.
Any insight would be appreciated.

PS - I like the apple icon for gravity.

it looks like you need to add stress stiffening 'AND' constrain the model. It can't get stiff without a restraint.

That did it - thanks
