"inertia constraints" in ADVNL 601, NX8

We are trying to do a simulation of an object with pressure loads but without any constraints. In a linear analysis we can use inertia relief, but 601 does not support this feature.

In I-DEAS we have used to do the simulation with a DOF-set (3 nodes with translational constraints) and 6 rigid body modes.

How can we do this simulation in NX8 and Nastran?
