Dear Ansys Team,

I sincerely hope that you can publish the theoretical basis for calculating the geometric stiffness matrix for solid elements. Compared to existing literature or textbooks, the method you use in ANSYS APDL for calculating the geometric stiffness matrix seems unique and difficult to trace. It would be a great pity if all the theories on geometric stiffness matrices for solid elements published over the past few decades turned out to be incorrect! Thank you for your response.

Best regards,
