Use mef physiscs to calculate the capacitance

Hello everyone, I have a problem with calculation of capacitance by using the physics "mef".
My model is a conductor disk isolated with paper placed in surrounding air. I want to calculate the capacitance of this disk at different frequencies, so I choose "frequency domain" as solver.
After computation, comsol does not provide such a variable of capacitance in global evaluation. Can someone tell me how to calculate the capacitance of the disk in this case?
Before, I always calculate the capacitance with this expression, 2*mef.intWe/real(mef.VCoil_1)^2
However, in this case, a disk is comprised of several independent conductor and I need to exciate each conductor separately. It means, I need to define a "single turn coil" for each conductor. So I can not use the equation above anymore, because there is only one total electric energy.
Thank you very much
