I'm attempting to do a 2 way FSI fluidand solid simulation on Ansys Fluent .

My problem is that in the solid domain , I keep getting this error that says there is excessive distortion of elements. I'm using an unstructured mesh.

I keep shrinking the mesh size, but that doesn't resolve the error. Eventually I got an error that the simulation exceeds the RAM limits because my mesh was too small.

How do I view the parts of the mesh with distorted elements?

How do I resolve this mshing problem?

Distorted elements may be due to the remeshing settings (smoothing has limits, and remeshing will eventually fail in certain circumstances) or the motion being too fast/large for a time step. 

To view the poor mesh, use a contour of cell quality (skewness), or in 3d create an iso-surface or register.
