hi, I am currently doing some simulations on comb drive via ANSYS Multiphysics to determine the relationship between lateral displacement of movable comb and the capacitance generated. However, I could not plot the graph of capacitance versus displacement. Can anyone help me out with this?

hi bro ...i have no solution for you but u have been doing it so plz plz help me.
i'm to run simulation on comb drive on ansys...but i'm not able to find how to. in work bench i don't find any option for the electromechanical system or electrostatic system then how to proceed ???

Ansys Workbench actually need you to create "air brick" between your structures which allow the electrostatic force to be calculated between your structure... You need to add a "command file" to your air geometry to specify the electrical property of the material and then add a command to your "static structure" so you can add your load for "named selection"... BTW, it's hard job to do so have fun decrypting all those infos...

I'm about to publicate an ANSYS electrostatic simulation walk through guide but it's still hidden for public because of a patent pending (structure on the guide)
