Hello, 

 

You can use system coupling to perform coupled simulation. Transient thermal can be coupled with CFX. Have a look at this: 14.1. Coupling CFX to an External Solver: System Coupling Simulations (ansys.com)

 

 

Additional, you can check this video tutorial for reference (though CFX is coupled with the steady-state thermal here) 

 

Thanks!
