Hi to everyone,
I'm trying to perform a simulation of a simple capacitor following this example: https://www.comsol.com/model/computing-capacitance-12689 and applying the dimensions of my system. I attach my model in this message: it is based in two metal plates (one changed and another grounded) in contact with two plastic plates and an air space in the middle. I've created "blk6" in the geometry to try if this way it worked but my initial model did not have it.
However, all I'm getting is a NaN result in the Maxwell capacitance (es.C11) and I do not know why. Also, no matter how I change the initial voltatge on the terminal, the value of the "Terminal voltatge" (es.V0_1) remain constant to 1.6364, which I found disturbing.
Am I missing any BCs? As I mentioned, I followed the steps of the tutorial above but with my geometry...
