Hi I have used electric current physics in AC/DC module to compute dipole moment of a spherical dielectric particle in external E field. Once I determined the type of particles and medium and their electrical properties in this physics, after running the program, I could obtain polarization vector explicitly at any point using comsol. on the other hand, I computed this parameter in another way. I set the whole system as medium and then computed electric field in every point of the medium .then by calculating manually the dipole moment of a spherical dielectric particle, I expected that the results will be same but the result from manually calculation overestimate this parameter nearly 2 order magnitude higher than that of comsol value. I would very much appreciate if you anybody know about the differences?
