Dear Konan90,
If you are an industrial user of NX, then consider the following suggestion:
You are studying a problem of full equilibrium between loads of action & reaction, then the INERTIA RELIEF feature is what you need.
Inertia relief is an advanced option that allows you to simulate unconstrained structures in the linear static solution with NX NASTRAN SOL 101, and in the linear static solution portions of SOLs 105 and 200. Typical applications of inertia relief include modeling an aircraft in flight, an automobile on a test track, or a satellite in space. The inertia relief method is a tool that you may not be familiar with.
Although the internal processing is somewhat complex, the interface to the inertia relief option is quite straightforward with NX NASTRAN. There are two ways to invoke the inertia relief:
• The first method is to specify the SUPORT entry explicitly by including PARAM,INREL,-1” in the Bulk Data Section.
• The second method (recommended) is to let NX Nastran select the SUPORT degrees of freedom automatically by including “PARAM,INREL,-2” in the Bulk Data Section.
Good luck and best regards,
Blas.
