Finite Element Analysis: L-19 NASTRAN Nonlinear FEA (Large Displacement & Geometric Nonlinear)

[@曾辉-o9b]

I have met 2 problems when I use the 106 solver to analysis a cantilever example.
1. When I check the section moment in large displacement analysis，I found the section moment less than it should be, even I limit the force error below 1%；
2. The follower force function not work.
