Static fields in a dynamic code

The Aether code (scheduled for release on September 30) culminates 12 years of my research on fast numerical methods for electrodynamics. The frequency-domain techniques were adapted from a program called RedWall that I developed for NIST. The time-domain strategies were tested in EMP3.

The application of Aether to pulsed-power devices is particularly interesting to me because I [...]

Simulating a pulsed-power system with Aether

The development of Aether continues on schedule for release in September. Capabilities for time-domain simulations are complete are we are creating several examples for the tutorial manual. In this example, the full three-dimensional capabilities of the code are used to characterize a pulsed power system. The goal is to design a dummy load to test a [...]

How many elements?

In using the 3D Amaze programs, the ever-present question is how to choose element sizes. The choice depends on the nature of the application, so there is no simple formula. Building a good mesh is an art, requiring experience and insight. I am acutely aware of the problem when I receive tech-help requests with user-prepared input [...]

Porting field information to OmniTrak with Mapper

I am consulting on a project that demands extremely accurate orbit calculations in a high magnetic field environment with saturated iron. Because the organization has another consultant with extensive experience with Maxwell 3D, the working plan is that he performs the magnetic field calculations. The resulting field values in the beam propagation region are transferred to [...]
