Trajectory Evaluator Assistant

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

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.

Recent Developments

1. Relativistic effects, which were previously ignored, are now taken into account -- these effects are a factor when dealing with particles moving at, or near, the speed of light.
2. Another new feature of the Assistant is that a coefficient of viscosity, also known as drag, can be added to the particle.
