Hello,
I am trying to couple electrostatics module with charge density continuity equation, for which these three equations need to be coupled:

The first two equations are provided in Electrostatics module; however, the last equation (charge density continuity equation), which calculates for the charge density is not included. The reason is that Electrostatic module assumes the material to be a perfect dielectric and therefore considers volumetric charge density (Image may be NSFW.

) to be zero. However, in my application, the material is not a perfect dielectric and so the corresponding paremeter is not zero.
Can anyone help how I can couple this equation and Electrostatics physics in COMSOL?
Thanks,
Nazanin
