Hello Deepak,

The cause of errors with highly distorted elements may vary, and the error messages provide clues to the areas you may need to consider for resolving your non-convergence issue. Firstly, I would suggest refining your model by reducing the element size to capture more details. Additionally, adding more steps through Analysis Settings > Step Controls can help in achieving convergence. Since you are modeling a non-linear problem, activating large deflection via Analysis Settings > Solver Controls is necessary. I hope these suggestions help!
