electrostatic solver questions
I recently started working with OpenFOAM and as I plan to do some electrostatic simulations. However I'm having some trouble with the electrostatic solver. The first question regards the code of the solver:
what do these two calculations do?
The second question is about the poisson equation
I'm using the charged_wire tutorial and from a technican's view I only know the voltage (=potential) of the wire, but not its charge. However when I set the boundary conditions to "calculated" or to "zeroGradient" I either get an error from the solver or the charge is zero. How can I solve this problem without knowing or calculating the charge in advance?
Thanks for your help!
