Segregated groups error in Stationary solver

Please login with a confirmed email address before reporting spam

Hi!

I have been following the "Frequency Selective Surface, Complementary Split Ring Resonator" model. While I was tweaking with it I found out that if I specify the deposited power as 1[W] (under port, Electromagnetic Waves, Frequency Domain) instead of leaving the Port input power, like in the original model, an error appears saying: "Constraint found for variables in different Segregated groups. Try to merge these groups."

I have tryed to put all the variables from the segregated groups in just one... but there is only one variable in all the segregaetd groups! The other one is empty. If I right-click in "Stationary solver 1" and click in "Fully coupled" then the solver doesn't converge.

My questions are: Why is there a problem in the 1rst place? Shouldn't everything be fine with the segregated steps if there's only one variable? What am I missing? How can I specify a deposited power withouth these problems?

Thanks :)
