Hi, I'm trying to simulate a varactor using air as dielectric between the plates. I based my analysis on the 2D-3D cantilever beam, using the Solid Mechanics, Moving Mesh and Electrostatics physics, but I can't get it to work. When I choose air as a material for a subdomain enclosing the structure, it need some mechanics parameters (E, Y, etc) that air does not have. How can I solve this? Many thanks
