The Trajectory Evaluator module permits the user to simulate the trajectory of a particle over time, either with:

• ElecNet models solved with the 3D electrostatic solver
• MagNet models solved with the 3D magnetostatic solver
• A combination of magnetic and electric fields from MagNet and ElecNet
• Coefficient of viscosity, also known as drag, can be added to the particle
• Relativistic effects

The Trajectory Evaluator program has a dialog interface. It is set up to run as a wizard, requesting input information from the user at each step before it is run. The program output includes:

• A text output file listing the position, velocity, and acceleration of the particle after each time step
• A representation of the particle's trajectory, drawn within the view of the model
• Graphs output of the position, velocity, and acceleration of the particle after each time step
• For electrostatic models - an AC field can be simulated by specifying a frequency
