Hi

COMSOL uses the "phasor approach so by using complex values for the amplitudes you can includ phase info to your frequency domain (harmonic) solver sweep analysis, check the doc, and I belive I have seen a model library of a 3 phse example, or was it on the model gallerie ?

It has alread ybeen discussed a few years ago, here on the Forum, the method is still the same ;)

Good luck

Hi

try a search on the Forum with PHASOR, and do the same on the help of COMSOL, and/or the PDF doc of the general user manual and the ACDC one

thanks for your quick answer.

I found this link and it appears it would be useful but I use COMSOL 4.1 and this model has been written by a higher version so I cant load it. is it possible to open that? what should I do?

thanks in advanced
