I performed an Static FEA analysis on an ellipsi between two parallel plates. The ellopsi and plates were assembled and matted by Tangent and Width constraints.
A pressure applied to the upper plate and the lower plate is fixed. The contact surfaces between the plates and ellipsi have roller/slider joints. After Running, I got this error:
"The Iterative Solver stopped.
The solver has numerical difficulties.
Model may not have adequate fixtures
No results saved."
I think the problem would be with contact surfaces because when running the ellipsi, it worked. I have tried different ways but it didn't work.
Any help would be appreciated.
