Iteration solver, RF module, 4.2a

Dear Comsol Users,

I have issue concerning iteration solver in RF Module,

I want to follow during the simulations linear residual and linear error, because as you know, these values change for every wavelength during the simulation (in my case wavelength is parameter).

My question is how to plot linear residual and linear error (I want to have wavelength on x axis and linear residual or linear error on y axis), and is that possible to plot it during the simulation, or just after it?


And my second question, by your experience, what is good iteration number in these simulations (is 10 000 good enough)?


Thank you very much on every help.
