MSC/NX Nastran Differences¶
The following is a list of differences between MSC and NX Nastran.
OFFT field on the CBAR/CBEAM. The OFFT field (default=’GGG’ for MSC) must be blank. I’m pretty sure GGG is the only form NX supports.
In NX, the nodes that MPCs/RBEs must actually exist and have associated mass/stiffness.
In NX, massless nodes can mess results up, e.g., two springs attached at a massless grid.
