# POT4A — A program for the direct solution of poisson's equation in complex geometries

## Description

Title of program: POT4A Catalogue Id: ACDB_v1_0 Nature of problem The program solves Poisson's equation in a rectangular region. Electrodes and dielectric interfaces can be included anywhere in the region. An electrode is defined as a line segment along which the potential is held at a given value. A dielectric interface is defined as a line across which the normal component of the electric displacement is held constant. The boundary conditions on the edge of the rectangle can be given value, zero normal gradient or periodic in the x-direction. In the y-direct ...
