Thank you so much Jim! I will use tshell elements to try to solve this issue.

Two quick questions:

You mentioned *ELEMENT_TSHELL rather than using *SECTION_TSHELL. Can I assign my 8-node (solid) elements a tshell section, or do I have to convert the solid elements to tshell elements before assigning them their respective section?

Also, any recommendation on the number of through thickness integration points or should I just leave the default value?
