Stellarium renders 3D photo-realistic skies in real time with OpenGL. It displays stars, constellations, planets and nebulae, and has many other features including multiple panoramic landscapes, fog ... [More] , light pollution simulation and a built-in scripting engine. Stellarium comes with a star catalogue of about 600 thousand stars and it is possible to download extra catalogues with up to 210 million stars. Stellarium has multiple sky cultures - see the constellations from the traditions of Polynesian, Inuit, Navajo, Korean, Lakota, Egyptian and Chinese astronomers, as well as the traditional Western constellations. It is also possible to visit other planets in the solar system - see what the sky looked like to the Apollo astronauts, or what the rings of Saturn looks like from Titan. [Less]

Celestia is an OpenGL-based 3D space simulation for Unix and Win32 that lets you travel through the solar system, to the stars, and even beyond the galaxy. Visit over 100,000 stars, 100 solar system bodies, and all known extrasolar planets.

KStars is a graphical desktop planetarium for KDE. It provides an accurate simulation of the night sky, as seen from any location on Earth, on any date. The display includes 40,000 stars, 13,000 ... [More] deep-sky objects, 2500 comets and asteroids, all 8 planets, and the Sun and Moon. [Less]

DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods. It supports the easy implementation of methods ... [More] like Finite Elements (FE), Finite Volumes (FV), and also Finite Differences (FD). [Less]

The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and ... [More] Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK. [Less]

Step is an interactive physical simulator. It works like this: you place some bodies on the scene, add some forces, such as gravity or springs, then click "Simulate" and Step shows you how your scene ... [More] will evolve according to the laws of physics. You can change every property of bodies and forces in your experiment (even during simulation) and see how this will change evolution of the experiment. With Step you can not only learn but feel how physics works! [Less]

Gravit is a gravity simulator which runs under Linux, Windows and Mac OS X. It's released under the GNU General Public License which makes it free. It uses Newtonian physics using the Barnes-Hut ... [More] N-body algorithm. Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns. It records the history of each particle so it can animate and display a path of its travels. At any stage you can rotate your view in 3D and zoom in and out. Gravit uses OpenGL with Lua, SDL, SDL_ttf and SDL_image. [Less]

NOTE: Because of the transition to a new language, Ohloh no longer tracks the lines of code Aciqra has. Open source planetarium written in C# with GDI+. Features several widgets including a ... [More] conjunction engine, transit/eclipse predicter and more. It shows the phases of planets, the moon and the classic constellations of the night sky. [Less]

Daisy is a mechanistic simulation model of the physical and biological processes in an agricultural field. It traces the fate of water, energy, carbon, nitrogen, and pesticides, both above and below ... [More] ground. The model is able to predict production, environmental impact in the form of leaching, and change in soil (carbon) quality over time. Another common use is as an upper boundary for a groundwater model. [Less]
