Import CST results to MWO

Hi folks,

i got a CST Structure with waveguide and differential discrete ports.

-> How can i import the simulation results to MWO?

The waveguide ports should be connected to 50 Ohm ports in MWO and between the differential discrete ports i want to put a lumped element circuit.

The whole thing should look the same like in CST DS!

Can someone explain the right way, how to export/import the block?

Thanks

PS.: If anybody knows, how to import to ADS would be great, too
