capacitance

Dear comsolers

I was working on electrostatic mode of application to calculate capacitance.I defined the electrodes as ports. comsol give me two sets of capacitance matrixes one the normal C11 and the other C11( from reaction of charges) and for my model the two values are not equal. Any point I have missed?

best regards

Hi

what is "not equal", they could show their difference from the way they are calculated, still probably representing the same parameter. Have you tried to refine your mesh a couple of times and check how these values evolve ?
