A two dimensional description of plasma charged sheath and ion extraction, including the complete plasma sheath equation, is proposed and reduced to a system of coupled fields, implemented with use of COMSOL Multiphysics.

A separate application of the weak form to the Hamilton-Jacobi and Poisson equations is also described, using five coupled fields.
