Hello,
the easiest way to calculate capacitance is the to use terminals. Here, the capacitance is measured to GND. If you apply a terminal sweep you can also calculate the relevant capacities C12, C13, ...
I have attached a simple model.
kind regards,
Levin Dieterle

Good morning Levin;
thank you very much for the response, by the terminal method i am assuming global evaluation -> capacitance?
do you by any chance have a tutorial on capacitance matrix's?
thank you for the help

gerhard

Hi,
I don't have a tutorial in COMSOL. However, here is a good explanation:

Hi Levin,
can you also provide me the model ?
I use COMSOL 4.3b.

Hello Dejan,
the model is attached to one of the previous posts.
Kind regards,

Hi I saw your discussion and I want to do exactly the same.
I have 3 electrodes (see figure attached). I want to know the capacity of each electrode with the grounded on the top of my box. I tried to implement everything as in your "capitance matrix.mph" file.
I have two grounds. I don't know if the matrix calculates the capacitance from the electrodes to the ground on the top of my box. Or the capacitance to my middle electrode, which is at ground.
How can I see which capacitance it gives me?
(and a small other question, if I apply a terminal on a good conductor, it is sufficient to just assign the terminal to one surface of the conductor, or do I have to select all surfaces)
