Hi,

I have a multiphysics problem. I can't figure out how to combine the two physics.

What I want to do is to solve RF EM waves (eigenfrequency) for a certain geometry (I prefer to use a torus therefore a 3D geometry) under the influence of a magnetic field created by a current carrying wire. I have the two physics (Magnetic Fields and Electromagnetic Waves) in my model. I can solve the two problems seperately, no problem.

But how can I make the EM Wave study to use the magnetic field created by the Magnetic Fields study in the solution?

Thanks.

Hello,

I am also experiencing some difficulties in combining two physics.
I am building a model for a SAW device.
I tested it using the "Piezoelectric Device" physics and I was able to see the admittance and other parameters.
Now, I want to obtain the S parameters. I introduced the "Electromagnetic Waves" physics and performed
some settings for it: added the ports and periodic conditions.

I started the simulations, but the parametric solver remains stuck around 20%.
Has any of you done this kind of simulation?
Do I need to operate some settings in order to get the two physics to work together?
Am I missing something?

Thank you,

Catalin B.
