SOL 601 Thermo-Mechanical Coupling Analysis

[Emiliano87]

I'm trying to learn how to make a two way iterative coupling on NX Nastran with the solver SOL 601. In the modeling guide it says It can be done in the chapter 9 but it is quite vague.
So far I realized I have to include the TRANOPT parameter in the TMCPARA entry. The COUP parameter for the same entry has to be 0 for iterative coupling and the TRANOPT I believe it has to be also 0 for transient thermal and structural.
For use of the automatic time stepping (ATS) for the thermal analysis solution the parameter is AUTO,1

The input file would be something like this, someone have experience with this?? Can give me some example or recommend some literature so I can study how to do this???

Hi Emiliano87,

I am looking into the same thing, but NX so far did not make it easy for me.

Did you find your solution? Do you have any suggestion on what to look at?

Thanks in advance!
