Dear all,
I have encountered a problem when solving capacitance in electrostatic model. I compute a simple parallel plate capacitance. I choose the upper plate as terminal, and set the voltage as 1V. But when I integral the surface charges on this surface, I found that it differs with the value of terminal charge or terminal capacitance.

Does anyone know why they are different, and which one I should chose as the capacitance of this structure. Thanks you very much!
