NASTRAN output coordinate system
Hi everybody, I am working with NASTRAN and I have a problem. When I use CQUAD4 elements, the stresses are given in the element reference system. That reference system is computed by NASTRAN using the element diagonal bisector method. Basically, the x-axis is between the node2 and node3 of the...- jmarcoj

rigid element for 3D analysis NASTRAN
I am working with 3D elements (CHEXA) using NASTRAN. I need to use rigid elements and I am using RBE2s but they are not rigid at all for 3D analysis. I have alread used those elements before (2D models) and they work great but when I try and connect brick elements the rigid elements RBE2 are not...- jmarcoj
