openEMS is an electromagnetic field solver using the FDTD method. It employs a fully 3D Cartesian and cylindrical coordinate graded mesh. Matlab (or Octave) is used as an easy and flexible scripting interface. Advanced Features include: multi-threading, SIMD (SSE), and MPI support for high speed FDTD.

Yet Another Dynamic Engine (YADE) is an extensible framework that is designed with dynamic libraries in a way that it is easy to add new numerical models and objects. There are four different models: Discrete Element Method based on spheres, a second method based on tetrahedra, modelling with lattice elements, and Finite Element Method.

Hasard is a pseudo-random number generator (PRNG) library. It includes multiple engines (algorithms): Park-Miller, Mersenne Twister, Linux device (/dev/urandom or /dev/random), and more. It has a simple but powerful API. For example, a PRNG seed can be generated using strong entropy (using a hardware random number generator like /dev/random on Linux). The library is written in C, and a Python binding is available. The word "hasard" is the French word for "randomness" or "chance".

The purpose of the glideinWMS is to provide a simple way to access the Grid resources. To achieve this without reinventing the wheel, glideinWMS is a Glidein-based WMS (Workload Management System) that works on top of Condor. Once setup, final users can submit regular Condor jobs to the local queue and the glidein factory will provide the computing resources behind the scenes. From the final user point of view, the Condor pool just magically grows and shrinks as needed.

OpendTect is a seismic interpretation software system. It enables you to process, visualize, and interpret multi-volume seismic data using attributes and modern visiualization techniques such as stereo viewing and volume rendering. Visualization elements can be moved freely through data space to interactively analyze data from stored volumes, or data calculated on-the-fly. For more advanced work, commercial plugins are available.

Cadabra is a computer algebra system designed specifically for the solution of problems encountered in field theory. It has extensive functionality for tensor polynomial simplification including multi-term symmetries, fermions and anti-commuting variables, Clifford algebras and Fierz transformations, implicit coordinate dependence, multiple index types, and many more. The input format is a subset of TeX. Both a command-line and a graphical interface are available.

Electron Gamma Shower (EGS) is a general purpose package for the Monte Carlo simulation of the coupled transport of electrons and photons in an arbitrary geometry for particles with energies from a few keV up to several TeV. Simulations can be performed in arbitrarily complex physical geometries, and a wide range of physical processes are modeled.
