I am trying to create symmetric surface charge distribution on a sphear in COMSOL (5.5). I know that, we can assign charge distribution (equal magnitude and opposite polarity) on the top and bottom of the sphere using the axisymmetric model in COMSOL. I wanted to make the charge distribution so that the sphere's right and left sides have charges of equal magnitude and opposite polarity. Is it possible to do it in COMSOL using 2D axisymmetric model?
