Translations:FEM EquationElectrostatic/15/en

The electrostatic equation provides these special settings:
 * : Calculates the capacitance matrix. The matrix contains the the point charges of the mesh knots.
 * : Calculates the electric energy.
 * : Calculates the electric field.
 * : Calculates the electric flux.
 * : Calculates the surface charge.
 * : File in which the capacitance matrix is being saved. It is only used if is set to true.
 * : If constant weighting for results is used.
 * : Potential difference in Volt for which the capacitance is calculated. It is only used if is set to false. Therefore in fact this setting specifies the voltage between the electrodes of a simple capacitor. Note that the given voltage has to be consistent with the potentials defined in the boundary conditions.
