I got three parallel plates. I set middle plate as electrode and the bottom one is ground. The top plate set as a object. I used the electrostatics mode and can calculate the middle to bottom capacitance by using global evaluation. How can I calculate the top and middle capacitance and top and bottom capacitance?

Thanks,

hi i am modeling a capacitor where i am giving 2 positve voltage to both the terminal so that the field is send outside and when i bring a object near it (floating potential) there should be change in capacitance which is not happening can anyone help. see the attachment

i am getting the wave but the capacitance dont change .
