hi all

how can i induce some phase dependent currents in comsol?
especially i wanna know how to make 3 currents with 120 degree different phase

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
