Combining static and time-harmonic analysis

Please login with a confirmed email address before reporting spam

Hi all!

I would like to analyze the magnetic field and current density in a coil (eg. Inductance and Resistance model - www.comsol.com/showroom/gallery/212/) and combine it with a static magnetic field (permanent magnet). How do I set up the model so that the static magnetic field does not vary time-harmonic?

Help greatly appreciated,
Johan Gustafsson (COMSOL newbie)

OK, I have realized that a small-signal analysis seems to be what I should do… so I will look into that...

I also need to use non-linear material parameters (B-H curve) in my model but there is no way around the assumption that the model is linear in a time-harmonic simulation I guess?

hi
i read your question
do you think you can help me
i'm trying to put AC small signal throw a coil and to see it voltage s time
do you think it is possible cause i tried a lot and could find the answer

Best regards,
Arye

thanks a lot
