Permanent Electrical Polarization in Material

Please login with a confirmed email address before reporting spam

I'd like to give a material a permanent electrical Polarization, but I can't find out if this possible in COMSOL. For the magnetic case, there exists a material property "Permanent Magnet Magnetic Flux Density Norm" under the AC/DC materials. This creates a material with a permanent M field inside (or that's my understanding). Does anyone know a way to do this for a permanent P field inside a material directly (like an electret).

The closest thing I can think to do is assign surface boundary charge densities and make the dielectric of the material inbetween the surface charge densities very large. This would look similar to a permanent polarization.
