Problem with selecting Multiphysics Domain/Boundary in Electromechanic Boundary Element Module

Please login with a confirmed email address before reporting spam

Hello,

I am trying to use Electromechanic Boundary Element for finding the vertical displacemnt of a cantilever (horizontal beam named as Electrode 2 (middle electrod)), due to electrostatic force of two fixed vertical Electrodes (Electrode 1 and 3) in a stationary step.

  • The fixed electrodes 1 and 3 have the Voltage of V=0 volte and the cantilever (Electrode 2)'s voltage sweeping through different numbers. Also there is a constant pressure applided on the cantilever(Electrode 2).

  • All the geometries are selected for Electrostatic Boundary Element Domain.

  • Electrod 2(Cantiever) is also selected for Solid Solid Mechanics domain.

The problem is that I cannot select any domain or boundary for the Electromechaical Interface (Multiphysics).

I have attached the model here. Please help. Thank you
