Hi,
I'm trying to find the pull-in voltage of a beam in 2D, essentially exactly as is done in the "Pull-in Voltage for a Biased Resonator-2D" model in the application gallery. The only differences are the dimensions (my bar is 100 nm thick, 15um wide) and the material (aluminium). I've tried different (types/sizes of) meshes but that doesn't help. The only thing that seems to help is to make the bar unrealistically thick (like 400 nm).
Usually I get an error something along the lines of "Maximum number of Newton iterations reached" , with a ton of inverted mesh elements in the warnings.
I'm pretty much out of ideas. All I want is to get the pull-in voltage but I don't know what I'm doing wrong. I've attached the simulation file.
