Capacity calculation via the electric field

Before I explain my problem, I apologize for all the grammatical mistakes i could make later. I'm french, is it an excuse ? ^^
For my master degree, I'm designing a Single Electron Invertor (SET). Right now, I try to evaluate all the capacity of my display.
I would like to do this job with two model :
- applying a potential, capaV, an all the metallic parts even the floating one, of the device and finding the capacity with an volume integration like
C= (1/capaV)*(es.Dx*es.nx+es.Dy*es.ny+es.Dz*es.nz)
This model works.
- applying a potential, capaV, an the metallic parts that are really connected to a potential and finding the floating potential of the other parts with a line integration via
V_float = - ( es.Ex*dl+es.Ey*dl+es.Ez*dl )
dl is the elementary displacement vector, where is this one in COMSOL ? That's the point of this topic ^^
Thank you for your futur responses,
Damien
