Procedures#
setup#
Link the user defined electric potential, electric field, charge etc. arrays to the corresponding array used in the library. Then, perform some necessary setup before actually solve the equation.
call electricContext%setup()
Important
setup must be called before the solve subroutines.
solve#
Solve the poisson equation, get the potential and electric field distribution from the charge and polarization distribution. This subroutine will solve the poisson equation based on the given constraints and update the electric potential and electric field in the context.
