Thank you for pointing that reference. It is helping a lot in the understanding of the problem.

I did some modifications on the script, and now I am receiving the following errors:

 

 *** ERROR ***                           CP =     141.031   TIME= 19:48:41
 Element 3763 has excessive thickness change.

 *** ERROR ***                           CP =     141.062   TIME= 19:48:51
 Element 1499 has excessive thickness change.

 *** ERROR ***                           CP =     141.094   TIME= 19:48:52
 Element 3486 has excessive thickness change.

 *** ERROR ***                           CP =     141.094   TIME= 19:48:53
 Element 3925 has excessive thickness change.

The updated nonlinear snippet of my script is this:

 

ANTYPE,0

SOLVE,

Is there anything else that I can do to get rid of the ”Element 3925 has excessive thickness change” error?

Since now I thank you very much for all the help
