Why haven't any ANSYS staff responded to me? Recently, I also tried Němec's theory (http://creativecommons.org/licenses/by/4.0/). However, the geometric stiffness matrix calculated from the theoretical formulas still doesn't match the one in ANSYS APDL. What could be the reason for this? I sincerely hope that someone knowledgeable can resolve this long-standing confusion for me.
