Hello, can someone help me how to tackle this problem? I am following the report written by 2014 SIMULIA Community Conference on nugget formation using resistance spot welding. I believe I followed the exact same procedure but my job gets aborted every time and I get the error listed on the attached. How do I correct them? Any help is highly appreciated. Thanks.

PS: Here is the report that I followed: https://www.3ds.com/fileadmin/PRODUCTS/SIMULIA/PDF/scc-papers/numerical-simulation-nugget-formation-14.pdf
