Steve,
When I analyze the attached file of a rigid element with prescribed displacement, I keep getting the following negative jacobian error until the file quit iterating:
"Negative jacobian was detected at element 1 at gauss point 1
jacobian = -1.#IND"
When I change the model's material to linear elastic, the file analyzes completely. I do get a strange unassigned rotation toward the end of the analysis though.
What am I not doing right?
Thanks,
Matt
