We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Is this a coupled thermal-Mechanical analysis or one way linkage of thermal transferred to Mechanical?

To do it entirely in a script means the script would have to take over the entire solution process. Instead you can insert a command snippet for each load step, and specify the load step for which those commands apply:

Or to do it with no commands, insert two contacts. One is the thermal contact. The other is Mechanical contact. For the thermal contact put a reasonable contact thermal conductance coefficient and a very low normal stiffness factor. In the second contact, you can put a very low thermal conductance coefficient and leave normal stiffness factor as program controlled or some reasonable value, like 0.01

For the Contact Step Control, you can see there is a normal stiffness factor where you can set a different one for each load step instead of dead/alive. But you can't vary the thermal conductance coefficient that same way.
