Error "no solution for input parameters"

Please login with a confirmed email address before reporting spam

Hi,
I want to simulate the farfield and the S 11-Parameter of a triangular bowtie antenna. When starting the simulation I get the following error:
- no solution for input parameters
-matrix contains zeros in the diagonal
-the solution does not converge

Can anyone tell me, how I can sove this problem?

Thanks

Dear Carina,

It’s always difficult to answer such questions without looking at the model. I'd suggest you take a look at the "Dipole Antenna" example from the application library. It should give you a good idea on how to setup an antenna model, also with s-parameter calculation.

Regards,

Andreas
