FreeSOLID is a library for collision detection of three-dimensional objects undergoing rigid motion and deformation. FreeSOLID is designed to be used in interactive 3D graphics applications.

Remember when you wrote your games in Pascal? Well continue that fine tradition by using JEDI-SDL! Which works with Delphi, Kylix, Free Pascal, Gnu Pascal and TMT Pascal. Cross-platform game develpment has never been easier!

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.

Motofit co-refines Neutron and X-ray reflectometry data, using the Abeles matrix / Parratt recursion and least squares fitting (Genetic algorithm or Levenberg Marquardt). It works in the IGOR Pro environment (TM Wavemetrics).

JGP is a GUI for gnuplot (http://www.gnuplot.info/). It is made for all those who just love gnuplot but who found that organizing a large number of datasets and plots from the command line is inconvenient. JGP uses gnuplot as plotting engine.

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.

J-ICE stands for Jmol interface for crystallographic and electronic properties. Is an extension of the powerful, platform independent molecular visualizer Jmol, towards crystallographic and electronic properties. More info will be given soon.

OpenFlower is a free and open source CFD code (for Linux and Windows) mainly intended to solve the turbulent incompressible Navier-Stokes equations with a LES approach. It can deal with arbitrary complex 3D geometries with its finite volume approach.

SpectrumGUI can generate filtered spectra for various x-ray tubes and can display attenuation coefficients for various materials. It also computes exposure and beam quality for various tube settings.

MatNMR is a highly flexible toolbox for processing 1D and 2D NMR/EPR spectra in MATLAB and creating high-quality 1D, 2D or 3D plots. Fully GUI and/or script-based.

sispread allows to simulate the dynamics of an hypothetic infectious disease within a contact network of connected people. It is intended to help people concerned by public health to easily perform epidemic simulations and to analyze their results.

toxic is a modern, physically correct global illumination renderer aiming to produce photorealistic images and animations. A number of plug-ins are under development to allow using toxic with various open source and commercial 3D modeling packages.

Simulate 2D physics with my engine entirely made in JavaScript. Modify live existing scenarii or create your own from scratch with the live editor. Try it on the demo web site! :) Note : If you intend to download and use the sources as it is, you need to host it as scenario resquests are made in AJAX.

Abacus Software is a specialized tool for controlling and analyzing Tausand Abacus devices (AB1002, AB1004, AB1502, AB1504, AB2502, and AB2504). It enables precise measurement of temporal coincidences with up to 2-nanosecond resolution, and real-time visualization of count data from one, two, or three channels simultaneously. The software includes advanced features such as adjustable line width, sampling time configuration, direct device settings control, and the ability to save both raw data and graphical outputs for later analysis. Designed for researchers, engineers, and educators, Abacus Software provides a user-friendly interface and powerful visualization tools to support high-resolution timing analysis in experimental setups.

Frustrated because you want to output a high-quality image from your C++ program but haven't found an easy, direct and fast way? Try PNGwriter. Written with scientific simulations in mind, PNGwriter allows you to plot to a PNG image pixel by pixel. * * *README* * * This is the last PNGwriter release that will be hosted on SourceForge.net. Please use the following site: https://github.com/pngwriter/pngwriter/releases to find all versions of PNGwriter including and later than 0.5.5. The PNGwriter website is still hosted on SourceForge.net: http://pngwriter.sourceforge.net Thank you! @individual61 @ax3l

PUPIL (Program for User Package Interface and Linking), is a software environment that allows developers to link quickly and efficiently together multiple pieces of software in a fully automated multi-scale simulation. More specifically, it supports QM/MM MD simulations where the user might choose among any of the different MD engines and QM engines, which are connected to PUPIL as external programs through a tiny specific interface. One of the main advantages here is that the user can use most of the functionalities that may have those external programs interfaced without the necessity to be reimplemented again on independent interfaces. In fact, this simulation interface concentrates all the common code involved in the coupling terms of the QM/MM approach.

The TLELib is the C++ library, which allows to read and write the TLE files very easy. It provides 2 main objects: tlelib::Node - object, operating with NORAD two lines elements data. It allows to parse the data from 2 or 3 lines and to output the data into strings in according to the TLE format. tlelib::Stream - stream, allowing to read the TLE data from some object of iostream type, and to write the data in TLE format into such object.
