integral solver

Am another newbie to CST and was wondering whether anyone could help.

I am in need to use the Integral Equation Solver, but for some reason its always disabled even when choosing the corresponding template (RCS-Large Object). I have defined my structure, frequency limits and used Discrete Face Port for excitation. All the other solvers are enabled apart from the I-solver. Any ideas why?

Hi VR4V6E39

I think you don't have the license for it.
to confirm it, go to file -> license. it will open
small window and there you can check if you
have it or not.

You are right, the license file show zero values for the Integral Equation Solver!

Thanks for your help!
