Reply To: Analysis of Fabric Plate

[peteroznewman]

What is the diameter of the plate?

What is the orientation of the plate relative to the coordinate system? 

You said the edges are free in Z translation only. Is Z in the plane of the plate or normal to the plate? 

You said this is an FSI analysis, what is the load on the plate?

Show the mesh on the plate because element size has a large effect on stress. Where is the highest stress?  Is it in a sharp interior corner?  Do you know what a Stress Singularity is?
