WavePacket (C++/Python)
Time-dependent simulation of open and closed quantum systems
Note: This package has been superseded by a Python-only package. See https://github.com/ulflor/wavepacket for the follow-up project. WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical... -

MaxFEM
Software for electromagnetic simulation
MaxFem is an open software package for electromagnetic simulation by using finite element methods. The package can solve problems in electrostatics, direct current, magnetostatics and eddy-currents. Since version 0.4.0, MaxFEM requires Python 3. We have moved the installers to the MaxFEM website (see below). In order to improve MaxFEM, we will require you to fill out a simple form before downloading them. -

Jljp
Calculates the voltage across a liquid junction between two solutions
An analogous project written in C# can be found here: https://github.com/swharden/JLJP Liquid junction potential calculator. It's a tool for scientists and engineers who have to do with electrochemistry and electrokinetics. When two solutions containing ions are put into contact, possibly through a porous diaphragm, a voltage develops across them. The calculation of the voltage is not trivial. The program is written in Java. Includes classes that can be included in other programs,... -

Virtual Reflectometer
Simulates basic reflectometer scans with X ray tracing.
With Virtual Reflectometer (VR), you can simulate the basic alignment scans of a basic X ray reflectometer (diffractometer) with a Goebel mirror using ray tracing. With this program, you can characterize reflectometers and get a reflectometer-dependent overillumination correction for X Ray Reflectivity (XRR) scans. The pogram serves as an educational tool for explaining alignment and for a proper overillumination correction of XRR data. !!Paper will be referenced!!. VR can be run by... -

VASPMO
Visualization of wavefunctions calculated by VASP (New release: v0.41)
VASPMO aims at visualizing wavefunctions (or molecular orbitals) from VASP calculations. It reads VASP's output files PROCAR and CONTCAR, and exports an *.out file in Gaussian's output format, which can be visualized by many popular visualization tools, such as JMol, Molekel, Chemcraft, Gabedit and Molden, etc. These tools can further generate *.cube files, which can be visualized by an even wider range of... -

F3DM
Finite Element Method on 3D Meshes
f3dmlib is a FEM library that can read, write and analyse 3D tetrahedral meshes, minimize a given functional, and refine the resulting meshes. The minimization is parallelized with OpenMP. Three main features in unstable 1.8.x version (available via GIT): quadratic elements, periodic boundary conditions, and the solver for scalar and electromagnetic wave equations. f3dmgeom is a collection of a few simple tools for creating surface meshes for tetgen. It can handle simple geometries only. -

MSU's Sparse Fourier Repository
The Home of DMSFT, AAFFT, GFFT, and MSFFT.
A collection of sparse Fourier transform codes developed by faculty at MSU. Currently codes for four different prototype sparse FFTs are here: 1.) DMSFT, implemented by Ruochuan Zhang. This is a fast, stable, noise robust, and *fully discrete* improvement on the ideas in GFFT below. It is THE BEST sparse FFT around!!! If you're looking for AAFFT, try this out first. 2.) AAFFT, implemented by Mark Iwen in 2008. This code is easy to use, and documented well, but not implemented...
