PLASIMO's particle tracker model calculates an electric field, then follows the motion of a user-specified collection of test particles in that field. Currently, it is assumed that the electric field is not affected by the particle charge.
The electrostatic fields are calculated from the Poisson equation, based on user-specified applied voltages on the electrode materials. Optionally, volume and/or surface charge profiles can be specified.
Example: Tracking of 'dust' particles
This example model shows tracking a number of 'dust' particles with composition (C64H64)20- in an electrostatic field. The particles are injected at user-specified locations with zero initial velocity.
