Zgoubi is a raytracing code. Since 1972 it pushes charged particles through accelerators and beam lines, by stepwise solution of Lorentz force equation - and their spins via Thomas-BMT differential equation. Zgoubi simulates beam dynamics and polarization in a variety of accelerators (storage ring, synchrotron, cyclotron, betatron, microtron, FFAG, multi-pass ERL, etc) and optical systems (beam lines, magnetic and electrostatic optical components, time-of-flight and mass...

These programs calculate high resolution conventional and scanning transmission electron microscope (CTEM, STEM) images of thin specimens from first principles using the multislice method for electrons in the energy range of approximately 60 keV to 1000 keV. The fundamental theory and usage are described in "Advanced Computing in Electron Microscopy" (Springer 2020) and Acta Cryst. A72 (2016) p. 1 by Earl J. Kirkland. Please refer to these for the theory of calculation and how to use...

Minsky brings system dynamics and monetary modelling to economics. Models are defined using flowcharts on a drawing canvas (as are Matlab's Simulink, Vensim, Stella, etc). Minsky's unique feature is the "Godley Table", which uses double entry bookkeeping to generate stock-flow consistent models of financial flows. Minsky is good for demonstrating mathematics too, with the most "math-like" interface in system dynamics. Sign up to Minsky's Patreon page (for as little as $1 a month) at...

ViennaSHE is a modern semiconductor device simulator for 1D, 2D and 3D device simulation. It relies on deterministic solutions of the Boltzmann Transport Equation using Spherical Harmonics Expansions.

The Artificial SEM Image Generator (ARTIMAGEN) is a library that generates artificial scanning electron microscope (SEM) and helium-ion microscope images of various samples, including gold-on-carbon resolution sample, or some semiconductor features.

LaueTools is an open-source project for white beam Laue x-ray microdiffraction data analysis including tools in image processing, peaks searching & indexing, crystal structure solving (orientation & strain) and data & grain mapping visualisation. Python 3 Code and new features are now at: https://gitlab.esrf.fr/micha/lauetools

I recently dug up some of my old simulations after to my surprise 3SAT and a theoretical expansion of boltzmann statistics reminded me I already simulated something like that but I didnt know how good a simulation it was. Check how the varying density and shape of electron clouds and soliton-like or fluid drop like blobs of field gradually start to point outward and get thinner, like a soliton is bell curve shaped as seen from outside. More importantly, compare the 2 halfs of electron cloud pressing against eachother after falling from random positions in 6 flat (x y z/size red green blue) or n dimensional sparse network of such bellcurves which overlap eachother to display the subtle changes in shape and dimension, and if you run it a few more times it sometimes randomly gets large or some parts very dark and moving inside the other, and I think I saw that electron orbital with the donut around the center and vibrating outward on the 2 axis. ...

Modal Interferometer Simulation Tool (MIST) is a MATLAB toolbox that can simulate arbitrary resonant optical systems in the paraxial beam approximation. It allows the user to define any optical setup (composed typically of laser sources, mirrors, lenses, electro-optical modulators and detectors) and to compute the static laser field at any point. It uses a Hermite-Gauss modal decomposition to simulate diffraction limited optics.
