All fields in drop-down menu for Schematic --> Simulation Project appear greyed out. Using CST Studio Suite  Learning Version 2024.

I can successfully do EM simulations, for example based on the Combine tutorial. But I can't do any Thermal simulation. The Tasks icon is also greyed out.

According to the web site CST Studio Learning allows EM-Thermal Coupling simulations but in practice it seems impossible to me.

Following instructions in 

file:///C:/Program%20Files%20(x86)/CST%20Studio%20Suite%202024/Documentation/CST%20Studio%20Suite%20-%20Thermal%20and%20Mechanical%20Simulation.pdf

is not possible.

Any help would be greatly appreciated.
