This paper explains the use of the charge-simulation technique with both Laplace's and Poisson's equations to map lines of field and equipotential contours of complex geometries. The geometries reported here are:
1.
(1) Plane electrodes used for the generation of curvilinear electrostatic fields. This configuration represents an asymmetric and unbounded electrostatic problem.
2.
(2) Corotron, with a shielded single corona wire. For this symmetric geometry, only the Laplacian case is considered.
3.
(3) Duct-type electrostatic precipitator geometry. Both the Laplacian and Poissonian fields are investigated for this doubly symmetric and bounded geometry.
