Dear all,
as mentioned in the title, I would know if the change (specifically an increase) of the relative tolerance in Time Dependent solver (but also in Stationary solver, why not) will reduce the time simulation. To be more precise, if I can get or not a decrease of the reciprocal of the step size faster and much linear than with lower tolerances (I have seen that a linear decrease of reciprocal of step size reduces drastically the solving time).
I would expect that an increase of relative tolerance will produce results more or less different than the real solution, but sometime one just need an order of magnitude of the results (especially at the beginning), thus it's more interesting reducing time solving than get very accurate results.
Thank you in advance!
Kind regards
