Calculate capacitance measurement between electrodes

Hi,

I have been able to simulate the electrical fields between 2 electrodes when one is given positive potential and the other is grounded.

However, after so much trying i am unable to get the capacitance and voltage values on any points between both electrodes.

Please help me, thank you!

Hi I saw your discussion and I want to do exactly the same.

The link you posted doesn't work anymore...

How can I get the capacitance between ground and a certain electrode of interest.

I have 3 electrodes (see figure attached). I want to know the capacity of each electrode with the grounded line on the top of my box.

Would be great if you can help me.
