[SOLVED] CST simulation in 180 hybrid coupler

[lalmohan]

Hello everyone,
I am trying to simulate 180 hybrid coupler using CST MWS. I define all 4 the ports using discrete port system. During simulation it showing some errors that I also attached over here.

Does any one know how to solve the problem?

I tried to attach the geometry but it system did not able to recognize the cst file.


Advance thanks for your kind help.

Thanks,
