FEMAP can support large deformation non linear calculations. To the right side of this post is a result animation of two beams subjected to moment perpendicular to the neutral axis. This is an exercise presented in the software manual (Large Deformation – Cantilever Beam). This is also a comparison test between standard and NASTRAN I-Beam. The nodes at one end are fixed and at the other end subjected to the load.
