Antenna calculation

Please login with a confirmed email address before reporting spam

Hello, I would like to ask for some advice. I am currently using the Electromagnetic Waves, Frequency Domain (RF Module) to build an antenna, with the frequency range set to 0.7 GHz - 5.1 GHz and a step size of 0.6. The calculation is very slow, but it eventually results in an error. The error message is: "Feature: Stationary Solver 1, failed to find a solution. The linear iteration diverged. The returned solution does not converge. Not all parameter steps were returned." Could you please tell me what might be causing this? Is it an issue with the model? Thank you very much!
