Problem STL files

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 at low incident energy

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 [...]

Electromagnetic busywork

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. [...]

FTabTool update

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 [...]
