"Conductive Media DC(emdc)" is ok. To get DEP, you only need to solve electric field distribution via emdc module. In the DEP force/velocity formula, you can set permitivity, conductivity, viscocity of medium, and permitivity, conductivity, diameter of particle in the constant setting and the DEP force/velocity formula in the expression settings.
