We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Try incrementing the load more slowly (increase the number of substeps or decrease the time step size). 

You do that under Analysis Settings.  Show a screen snapshot of your analysis settings before and after you make a change.

Named Selections for the offending element can be created via the Identify Element Violations property on the Solution Information Object.

Do that and look at where the element that has become highly distorted is located. Reply with a screen snapshot.

 You may need to improve your mesh to obtain elements with better aspect ratios.

You do that by simplifying the geometry, especially near the highly distorted elements. You may get better element shapes by slicing the solid into pieces and reassembling the pieces using the Share button in SpaceClaim.
