Floating conductor boundary for electrostatics #244

Open sebastiangrimberg opened 1 month ago

See, for example, https://ieeexplore.ieee.org/document/538859. Essentially we wish to impose V = constant on a boundary surface.

This can be achieved by first considering floating conductors as terminals, and then eliminating these entries from the capacitance matrix and correcting the non-floating terminal capacitance matrix and corresponding field solutions.
