Poisson Embedding

Poisson solves the boundary value problem for conductors and simple charge-density distributions using the relaxation method. Contour and field plot visualizations are available.

Poisson calculates electrostatic potentials by numerically solving Poisson's equation in the presence of spherical and rectangular conductors, charge densities, and dielectrics. The gradient of this potential is then calculated in order to display the electric field and the divergence is calculated to display the induced charge. Although Poisson may be used in interactive mode using a click and drag metaphor, it is designed to be scripted. Many options, such as dielectrics, are only available through script.

Poisson is embedded using the following html tag:
