Could you help me with simulating drag force and dielectrophoresis force in comsol by using AC/DC module?

Please login with a confirmed email address before reporting spam

I'm trying to apply a nonuniform electric field and create a dielectrophoretic force in a channel and put a particle in the middle of the channel. I added these 2 physics, creeping flow and electrostatics. I don't know how to simulate Dielectrophoresis force and drag force acting on particles in a fluid.

I chose particle tracing for fluid flow module, But the problem is that I don't want to get the particle trajectories, I chose it just because it has drag force and dielectric force. I found out that I can create drag force and dielectrophoresis force in AC/DC module, but I don't know, how?

Anyone can help me to see what happened? your help is really appreciated.
