Convergence check

[aoshen]

Can I check the convergence of an EM simulation, after I close the 'x.smash' file and reopen it?
Because when I reopen the simulation file, the 'Task Manager' window is empty.
I checked the log file in the result folder, but I found nothing about convergence.

If you are using version 8 you should be able to see the convergence as one of your simulation outputs alongside the sensors.

However, if you went to your results folder and don't see an x_Output.log with convergence information inside, it may not have been recorded. This can happen if the runtime is too short or if you removed the auto-termination condition.

Thanks, the simulation file is from sim4life V7.2, so I'm not able to see the convergence in the analysis window.

Fortunately, I have found the "x_Output.log" in my Results file, but I can't understand it.

Could you please explain the meaning of each row in the results file?

Take an example like this:

Sensor 'Capacitor_L 1  (Current L)'
Exponential moving average factor 0.894427, Harmonic steady state detector: time step 3.08414e-10s, frequency 64MHz, approximate quarter period 3.70097e-09s, target convergence level -50 dB

By the way, what's the meaning of "convergence", and which value or formula do we use to express this variable?

Thank you very much for your prompt response!
