General Mission Analysis Tool
Do you want to go to Mars but don't know when to leave or how much to bring? Do you want to study Earth protection by planning a mission to a near-Earth asteroid? The General Mission Analysis Tool (GMAT) is an open-source space mission design tool to help you answer these and many other space flight challenges. GMAT is developed by a team of NASA, private industry, and public and private contributors. The GMAT development team is pleased to announce the release of GMAT version R2017a. For a complete list of new features, compatibility changes, and bug fixes, see the Release Notes. Below are just some of the new capabilities contained in this release. • New navigation data types • Preliminary Kalman filter • STK ephemeris propagation • Utility for managing data files (EOP etc.) • Collocation library • Preliminary API interface • Second level editing of navigation data
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. 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.

qsims simulates quantum dynamics with an (almost) arbitrary time-dependent Hamiltonian. qsims uses a Chebychev polynomial expansion of the Schrodinger propagator, and the pseudospectral method developed by R. Kosloff.
Time-dependent simulation of open and closed quantum systems
WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics for distinguishable particles. It can be used to solve one or more (i.e. coupled channels) time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can simulate modern experiments using ultrashort light pulses in photo-induced physics or chemistry. WavePacket is especially suitable for teaching of quantum mechanics as well as for research projects in physics, chemistry, and scientific computing. The present C++ version is an object-oriented rewrite of the existing Matlab version aiming to be more flexible. In particular, the goals are easy handling of open and closed systems and support for unusual setups.

A Physics Theory for Unifying Classical, Quantum and Relativistic Phys
This is the Official Software of the Pi-Space Physics Theory created by Martin Brady. I have a B.Sc. in Computer Applications from Dublin City University and I have an interest in software implementation of Physics. The Theory includes a Quantum Theory of Gravity as well as a reworking of Classical versions of Newton's Formulas. The Theory is based on a set of Relativistic Diagrams called Pi-Space Diagrams for those new to the Theory.

ACCORD is a C library for composition of scanning electron or helium-ion microscope images with correction of drift. It produces significantly more accurate images than the traditional imaging techniques and also provides drift trajectories.
Acoustic Simulation Library for Frequency and Time Domain Simulations.
ART is a flexible simulation framework for wind instruments. It includes a growing library of modelling elements. So far bore discontinuities, branches, tone holes, cylindrical and conical tubes, Bessel horns and bent tubes are available for frequency domain modelling. In the time domain generic bidirectional propagation elements, scattering elements, fractional delays, convolution with reflection functions and general z-domain networks are available and can be described using MuParserX expressions. Cylindrical and conical ducts can also be defined based on their geometry. Available models and their parameters can be enumerated and combined to form simulators for complex acoustical structures. Parameters can be specified symbolically by expressions containing other parameter values or global variables. Dependencies between parameters are resolved at run time. However, MuParserX expressions are compiled at design time. Zero-delay loops are detected and reported.
Cagliari-Orsay model for anharmonic molecular spectra in 2nd order PT
