Hi there,

I wanted to couple transient structural with fluent, but keep having dynamic mesh issue - either 1) update-dynamic-mesh failed: negative cell volume detected or 2) divergence detected in AMG solverressure correction.

Attached link is the rigid body motion I am working on.

Actually my dynamic mesh setting works pretty well when the center hinge is anchored. In contrast, when the center hinge is moving as in the movie, it's very difficult to find an ideal setting for the dynamic remeshing.

I was just wondering if I could address this issue by just changing the dynamic mesh settings (e.g., smoothing, layering, remeshing).

I would appreciate any inputs!

Thank you for your help.
