Electron Optics with
- Coulomb repulsion
- Relativistic Effects
- Coupling between electron beam and applied electric/magnetic fields
- Thermionic emission and field emission
For thermionic emission, coupling with thermal analysis.
Note that competitors such as Altair Hyperworks (partnered with VSim) and CST (Computer Simulation Technologies, now owned by Daussalt) and COMSOL have electron optics with multiphysics. Surprisingly, ANSYS does not have electron optics.
Additionally, CST and COMSOL have very poor live support with little in the way of written and YouTube tutorials.
Maybe SimScale can get ahead by having a gold standard in its physics offerings and support.
