In Harmonic Balance, is it possible to force a value of maxperiods lower than 100. Even if I set a lower value, 100 iterations are made anyway.
I see you've already been discussing this with an AE via SR 42727384 - we had an internal discussion about this yesterday.
It only takes 100 (50 normally, I think it depends on other settings) iterations if it hasn't converged before then. Setting it lower won't help it converge, but would potentially just let it give up sooner. Anyway, right now it is not possible to set maxperiods lower than the default - it's normally used to allow more iterations for it to converge, which is only rarely going to help.
The fundamental issue that needs resolving is why it is not converging - or if that convergence is slow. You should work that through with the AE dealing with your service request. We're also planning on documenting the behaviour of maxperiods so that it is clearer.
In reply to Andrew Beckett:
Thank you very much.
How can I force maperiods=50 (in my case the number of iterations is always 100)?
In reply to Aldo2:
My guess is that it is dependent upon either errpreset or maybe if you're simulating an oscillator. Or maybe it's the number of tones. Unfortunately I don't have an example to hand which doesn't converge so I can't test this very easily (not in the office right now so have limited things to try out). As I said, best to continue this through your existing service request to avoid two of us working on this in parallel.
Thanks for your understanding.
Ok. Thank you.
