Dielectrophoresis force simulation. Which module should I use?

Hello, thanks for looking at this problem!
I am a new user of COMSOL. The version I am using is 3.5.
What I am trying to do is get an idea of dielectrophoresis force of a microparticle between two electrodes inside a micro-channel. I am trying to integrate Maxwell stress tensor over the surface of microparticle. The procedure described in several papers are all using electrostatic module. But I couldn't figure out how to input conductivity of the material (e.g. water) in this module. When I switch to AC module, there is no way to get displacement and other information to integrate Maxwell stress tensor. How can I solve this problem?
Thank you so much!!
Best regards
Peng

Hi Peng,
I think AC/DC module is the good one to use in that case. In "Physics" and by choosing the various domains of your geometry (subdomains or boundary) , you will have an access of the options you want ( electric displacement, permittivity, conductivity,...)
Hope it helps

Hi
I too am interested in modeling DEP in Comsol. Please let me know if you've had any successes.
