Can you share your Ansys model (.cdb )?

Nathan Madutujuh

A solid finite element usually has only 3 dof for each node. The rotation can be calculate the twist angle of the section axis compared to the original section axis position. The current deformed section axis can be calculated from the new position of each node in the solid element. This calculation must be done for each section along the element length.
