For the flow in 3dic compiler you will need to use the redhawk-sc license as well and redhawk-sc_electrothermal.  From the tools you can download it looks like you have the redhawk-sc_electrothermal license, is that correct?  If so you should also have redhawk-sc license and electrothermal is a sub feature of redhawk-sc.

Do you have access to Ansys Learning Hub (ALH).  We do have training material for a 2.5D design.  An interposer and 2 dies.  This example can be used for power and thermal integrity.  The training material for this in an Ansys only flow is available on ALH.
