Hi All,
i have a 3D-PMSM-Modell and after 1 days of simulation (stationary) i got this. it wont converge. Normally ErrEst (estimated error) should smaller than 1e-3 at damping 1 to converge.
Have somebody idea, are this result reliable enough? if i used the result for Heat transfer (HT). What kind of result would be expected?
