staticSimionPASim
=================

Simulates the particle trajectories of an ensemble of charged particles in an arbitrary electric potential distribution and electrode geometry, defined by a SIMION potential array. The particles interact by electric particle-particle force (space charge) which is calculated by an serial version of a Barnes-Hut tree.
