Hello, I am currently doing a Triboelectric nanogenerator simulation in Comsol 5.6 version. I am using electromechanics physics. It comes with electrostatics, solid mechanics and moving mesh. I know how to use electrostatics and solid mechanics part, but ı do not know how to apply moving mesh which has two parts deforming domain 1 and symmetry roller 1. I could not find a relevant tutorial. I am using a time-dependent study. I just want my upper part of the generator to move up and down, I will use solutions to make displacement vs time graph. Could anyone help me? Thanks.
