Sir,
In frequency domain study, in stationary solver there are options like automatic, linear, linearized and non'linear which is to be shown. Is there any need to change the relative tolerance value

Hi

I use 80-90% ofthe time the defaut settings, even I would say I start always with the default settings, it's only when the solver does not converge, and I'm convinced that nothing else than the solver tweaking is in cause, then I take a closer look to those settings

But that is my way, others that have their own ideas on which solver might be more rapid tendto tweak quicker, it's all wery model dependent

Good luck
