Hi,

I am trying to test few things on different Magnetoelectric devices using simulation in COMSOL.

Can someone please suggest a way to apply a biased magnetic field in COMSOL in one study step which will be a type of frequency domain or similar?

I mean the magnetic field needs to have a DC component and an AC component - so the AC magnetic field will oscillate around the bias field (please see the file attached for an example). The thing is that I need for it to be done in ONE study step in the frequency domain, without the perturbation study type. I want to sweep through different frequencies and get the output voltage at each frequency. Maybe instead of DC field, the material can have some initial magnetization or initial strain which will give similar effect, but I am not sure if that will work or enable me to do it in one step.

Please advise.

I tried COMSOL support already and they seem to struggle to suggest a solution, which I hope does exist.

Thank you and best regards,

Olga.
