Information
The capacitance (C) is calculated from the surface area (A), length of the gap (L), and the permittivity (ε) assuming that the charges are uniformly distributed over (infinite) parallel planes.
If setVelocity is true, then the material exits with the
velocity of the inert connector. Typically, that connector should be connected to the stationary solid,
in which case heat will be generated if material arrives with a nonzero velocity. That heat is rejected to the same connector.
