Last week I received the type of tech-help inquiry that accounts for 83% of strokes among software developers. A user reported that results from our 3D code did not agree with numbers he obtained from one of those free magnet calculators that you find on the Internet. Given the choice of believing a finite-element, multi-processor program [...]
An OmniTrak feature that may not be familiar is the capability to include two-dimensional field solutions from Estat or PerMag. I recently had a consulting job where this was just the thing I needed, so I thought I would take this opportunity to review why the feature is valuable and how to apply it.
There are two [...]
A customer recently asked about color-coding particle trajectories in Trak and OmniView. He wanted to start particles from an input list (PRT) and to plot trajectories with colors determined by the injection kinetic energy. This is a fairly tall order, but I came up with a procedure for plotting up to three classes of particles using [...]
Trak can handle multiple charged-particle species in a single run. The program can even determine self-consistent space-charge-limited emission for different particle types from multiple emission surfaces. When responding to a user question about run setups, I realized that there was no example to illustrate the capability in the Trak library. This example describes the example BIPOLAR [...]
We recently added the capability to export three-dimensional power-density distributions calculated by Aether in the RF mode to HeatWave for thermal simulations. A user suggested an application – heating of dielectric objects in a microwave resonator. We carried out detailed calculations for this application to test the new code features and to confirm the existing capabilities [...]
