How to couple a thermal and structural analysis in NX?

Hi,

I am trying to solve a thermal solution and structural deformation simultaneously.

I know I can map a thermal solution to a structural solution and use that temperature map as a pre-load after the fact that the thermal solution is completed. However, I need both to be coupled an solved simultaneously (or at least close to being simultaneous), as transient solution.

e.g. For time step 1, solve thermal solution as sub-steps --> feed solution to structural analysis --> solve structural solution as sub-steps --> feed solution for time step 2--> solve thermal solution for time step 2... etc....

It seems it is possible to do so in NX nastran. But I cannot find any steps for doing that. I tried using NX Nastran and NX Multiphysics. But both only allow me to do either a structural or thermal analysis separately.

Does anyone has any suggestion? Does it require any special license?

Thanks!
Elaine
