Field Precision software tips

This note gives suggestions on modeling floating electrodes in EStat, RFE2, HiPhi or RFE3. A floating electrode is a piece of metal whose potential you don’t know in advance. For example, metal grading rings in an pulsed-voltage insulator have potentials determined by capacitive division in the structure.

To begin, consider a dielectric-type electrostatic calculation in EStat or [...]

There are many options to terminate orbits in the 3D charged-particle code OmniTrak. We have had several user reports that particles appeared to stop mysteriously part way through the solution volume. This article discusses how to diagnose and correct the problem.

The first and most critical step is to find out why the particles are stopping. Add [...]
