Air Domain and a vacuum

Please login with a confirmed email address before reporting spam

I'm new to Comsol and trying to fix errors in my model of two quadrupoles focusing a stream of particles down a beam line. Looking at the example models I see the ones having to do with magnetic fields have a domain around the model which is usually air.

I've added a cylinder around my model and defined the material as air. But I was wondering if there was a way to do this while having my beam line be a vacuum.

Thanks
Erin

Erin,

in COMSOL the materials are represented by their properties in the model. I assume that in your electromagnetic application the relevant material properties for air and vacuum are exactly identical.

Cheers
Edgar

I didn't realize that. Thank you!
