Capacitance calculation

Hi,

first of all, I am very new to Comsol Multiphysics. So I hope that you can help me a bit with my problem.


Overall, I want to calculate the electrical capacitances between wires. So I build my model in comsol, defined materials and potentials, meshed and let comsol calculate it.

My question is, how I can get the capacitance? I think that I have to calculate them with the electric field energy. But how can I get it?

I hope you can help me a bit. Thanks a lot!
