Hello Comsol,

I am trying to compute a model in electromagnetic waves, frequency domain. So, I have to find out two results, one with time modulation and other with without time modulation. When I simulated for without time modulation, I got the correct result and simulation working well. But, when I added time modulated equation in variables definition, I started getting errors. Initially, I got an error that the model is not converging, after I increased the number to iterations but as soon as I did that I get stuck in new error ofsingular matrix and returned is not converged. not all parameter steps returned.

I am attatching the model file with this message. Please let me know how can I reslove this issue.
