In building three-dimensional finite-element solutions, the eternal hope is the faultless transfer of geometric information from CAD programs. In this scenario, mesh generation is a leisurely activity, simply a matter of clicking a few commands. Unfortunately, reality often intrudes. We live in a world where people can’t even make a universal phone charger, let alone [...]
Electron backscatter in an important process in models of high-voltage X-ray sources and collectors for high-power microwave tubes. A GamBet user reported observing backscatter ratios below the expected values. He had made two changes in our standard example of electron backscatter from a gold foil:
Reduction of the incident electron energy by an order of magnitude.
Initiation [...]
As we move forward with Aether (our 3D electromagnetic program), we are simultaneously improving the 2D codes EMP and WaveSim. There are two reasons: 1) we are creating benchmark examples of increasing complexity to test the new code and 2) the 2D programs will be combined with Aether in the new Advanced Electromagnetic Design Suite. [...]
The OmniTrak code for charged particle dynamics can import information on electric and magnetic fields directly from solutions created by our codes HiPhi and Magnum or from field maps. A field map is a text file with a simple and well-documented format that gives values of (Ex,Ey,Ez) or (Bx,By,Bz) on a uniform Cartesian mesh. The [...]
