A SIMION potential array (PA) is a 2D or 3D rectangular grid (sometimes called a “mesh”) of points in space. It’s purpose is to store electrode geometries and/or potentials at each point in that geometry.

Each point defines

• a potential (electrostatic or scalar magnetic potential)
• a flag marking the point as an electrode or non-electrode point.

A PA also contains a header section with general information about the PA such as the dimensions of the PA and whether the PA has symmetry or mirroring.
