Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.
A Portable General-Purpose Computer Algebra System
REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers. It can be used interactively for simple calculations but also provides a flexible and expressive user programming language. The development of the REDUCE computer algebra system was started in the 1960s by Anthony C. Hearn. Since then, many scientists from all over the world have contributed to its development. REDUCE has a long and distinguished place in the history of computer algebra systems. Other systems that address some of the same issues but sometimes with rather different emphasis are Axiom, Derive, Macsyma (Maxima), Maple, Mathematica and MuPAD. REDUCE primarily runs on either Portable Standard Lisp (PSL) or Codemist Standard Lisp (CSL), both of which are included in the SourceForge distribution. By modern standards, REDUCE is a surprisingly small and compact application, which runs well on all major operating systems.

Aciqra is a virtual planetarium and sky mapping program which tracks celestial bodies including planets, deep sky objects and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past. It includes the 2.5 million stars of the Tycho-2 catalog supplemented by data of 120,000 stars from the Hipparcos catalog, 13,000 deep space objects from the NGC and IC catalogs and a large number of asteroids and comets from the Minor Planet Center. The program is platform-independent and can be made to work on most modern computers that support OpenGL.
Dynamics of quantum systems, controlled by external fields
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, including quantum optimal control. The graphical capabilities allow visualization 'on the fly', including Wigner transforms to phase space. A description of WavePacket can be found in our manuscript at http://dx.doi.org/10.1016/j.cpc.2016.12.007. For examples / movies, see also the Wiki pages of the WavePacket main project. First established in 2004, the present Matlab version is in a stable, mature state. Further development mainly by Burkhard Schmidt at Free University Berlin

Starting with a seed airfoil, Xoptfoil uses particle swarm, genetic algorithm and direct search methodologies to perturb the geometry and maximize performance. The user selects a number of operating points over which to optimize, desired constraints, and the optimizer does the rest.
A program for fitting structural models to small angle scattering data
SASfit has been written for analyzing and plotting small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, Porod constant. Furthermore it can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of (global) parameters. This last option is especially important in contrast variation experiments or measurements with polarised neutrons. The global fit helps to determine fit parameters unambiguously which by analysing a single curve would be otherwise strongly correlated.

VHF-UHF propagation prediction and radio coverage analysis tool.
QRadioPredict is an experimental software for VHF-UHF propagation prediction and radio coverage analysis. Currently it works on Linux and Windows 32 bit (Vista tested). Can be used as a repeater site planing tool. Uses OpenStreetMap tiles or public sattelite imagery as background. Elevation profiles are taken from NASA 1 degree SRTM 3 arcsec elevation files (*.hgt) obtainable from various sources. Uses a new algorithm for glound clutter attenuation prediction, based on a ray model. Terrain type data is taken from Corine CLC2006 shapefiles, which gives great accuracy for all of Europe, or from any other land cover data such as VMAP0 shapefiles. Has an internal APRS client which can be used to display stations as a landmark. Can use antenna radiation patterns generated by 4NEC2 or other NEC2 compatible antenna modelling programs. QRadioPredict can operate as a traditional standalone program or can be connected to Flightgear for real-time radio analysis.

Software for molecular simulations and trajectory analysis
We are proud to introduce version 3 of CAMPARI. This is a big step from version 2 primarily due to the comprehensive OpenMP (threads parallelism) support and due to significant improvements in both usability and performance. We have also again added a number of new algorithms from the recent literature, and CAMPARI of course continues to support the ABSINTH force field paradigm and implicit solvation model. CAMPARI is a joint package for performing and analyzing molecular simulations, in particular of polymers of biological relevance. It focuses on a wide availability of algorithms for (advanced) sampling and is capable of combining Monte Carlo and molecular dynamics sampling in seamless fashion. CAMPARI offers the user a very high level of control over all implemented features. For more information and features, please refer to the project's homepage at http://campari.sourceforge.net. Version 2 is no longer actively maintained but the final version continues to be available.
