Singular matrix when changing mode

Please login with a confirmed email address before reporting spam

I have a model of WG mode conversion. If I change one of the ports from TE01 to TM01, the model gives me "singular matrix" error on the changed mode S pars. Evry other setting in the model is unchanged, I only change 1 mode.
