Open Source Desktop Operating Systems Simulation Software

FRAME3DD is a program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.

gVirtualXRay is a C++ library to simulate X-ray imaging. It is based on the Beer-Lambert law to compute the absorption of light (i.e. photons) by 3D objects (here polygon meshes). It is implemented on the graphics processing unit (GPU) using the OpenGL Shading Language (GLSL). SimpleGVXR is a smaller library build on the top of gVirtualXRay. It provides wrappers to Python, R, Ruby, Tcl, C#, Java, and GNU Octave.

Library for ion optics, plasma extraction and space charge dominated ion beam transport.

GLUI is a GLUT-based C++ user interface library which provides controls such as buttons, checkboxes, radio buttons, and spinners to OpenGL applications. It is window-system independent, using GLUT or FreeGLUT.

This is the native MS windows release of OpenFOAM, an open source toolbox for Computational Fluid Dynamics (CFD). It was built with MinGW C++ as a set of native windows applications, which improves performance and eliminates the need for Unix emulations.

!!! This project is currently CLOSED. There is a new version of API available under LGPL license at https://github.com/gehtsoft-usa/BallisticCalculator1 There is a new version of application in progress (ported to net framework 5.0) https://github.com/nikolaygekht/ballistic.calculator.app Ballisitic Calculator based on JBM's implementation 3-degree of freedom model, ported to C#, improved to support metric system and extended by some math from Litz's "Applied Ballistic" book. Calculator displays ballistic tables, graphs, comparison graph and reticle images. The application is free to use under GNU license

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.

Wavefront is a programme for simulating 2D acoustic systems, with a particular emphasis on determining wavefront shapes at the mouths of horns. It accepts CAD drawings in DXF format and produces animated displays of wave propagation as well as exporting various data as text files. It is GPL software and runns on Linux and Windows.

This software has moved to http://www.poissonboltzmann.org/.

It started as a simple physics API for educational purposes, but now its development is clearly focused on gaming and will be incorporated to a next-gen engine.

All pairs n-body simulation of electromagnetic forces on charged particles, adapted from Nvidia SDK 3.2 sample. Uses Lorentz force from EM fields via the Biot-Savart law for moving charged particles (uses relative velocity). Relativistic.

Time Engine.

MBDyn (1.2.6) as C/C++ project in the Eclipse/CDT-IDE ported from its original autotools-build-system for adding the comfort of a modern C/C++ developement environment to the programming phase. For ++info on MBDyn see <http://www.aero.polimi.it/~mbdyn/>

MBDyn_sim_suite is a collection of free pre&post-processing tools and simulation models for the open-source multi-body analysis software MBDyn forming a general purpose simulation environment for structural dynamics with an emphasis on wind turbines.

Magnetic Drug Targeting (MDT) simulation and visualization in traversal and longtitudinal mode.

Magneticle is a 3D OpenGL physical simulation that applies the Biot-Savart law to charged particles operating inside a magnetic field produced by a current-carrying wire modeled as an arbitrary space curve.

NanoHive is a modular simulator used for modelling the physical world at a nanometer scale. The intended purpose of the simulator is to act as a tool for the study and development of nanotech entities. The project will also focus on the simulation of complex biological applications such as Targeted Drug Delivery by simulating nanowires, magnetic nanoparticles and others. Updates will follow from January 2017.

QCS is a quantum computer simulation written by Philipp Jungmann, Torsten Mandel and Maximilian Plenert as a software project under Dr. Michael Winckler (IWR) and Dr. Jian-Wei Pan (PI), University of Heidelberg.

Spasmos is a Python package that allows scientists to simulate the dynamics of highly collisional plasmas using a number of numerical methods.

TROPICS - Trajectory of Particle In a Crystal Simulator программный комплекс для моделирования траекторий движения быстрых заряженных частиц в осевых и плоскостных каналах кристалла под ОС Windows и Linux. Комплекс легко расширяется плагинами, может работать как в графическом режиме, так и в консольном для простого встраивания в другие программы. Комплекс обладает богатым количеством возможностей и настроек. Для построения графиков используется графическая библиотека MathGL (http://mathgl.sf.net/).

UPDATED VERSION ON GITHUB! http://github.com/AtiX/wavesim This is a physically correct simulation of waves on a surface, for example water-waves. It can also be used to simulate Microwaves, and has features like the support for different refraction indices, different wave sources and custom borders. Therefore, experiments like the double-slit-experiment can be easily simulated.

YAFEMS (Yet Another Finite Element Method Solver) is a FEM solver for Linux and WIndows that reads a MED mesh file produced by Salome (http://www.salome-platform.org/) with certain groups created into the mesh, and with the help of an input text file (.yaf), performs a 3D or 2D plane stress or plane strain analysis and creates results in plain text format and in MED format. This way a complete analysis can be carried inside Salome, where a mesh file can be created, exported and read by YAFEMS with the help of a .yaf input file and post-processed within Salome using ParaView. New in v0.4 - More performance boost due to the implementation of the Cuthill-McKee algorithm.

lib_3d_mec_ginac is a library for symbolic multibody system dynamics. It can be used standalone, although it will be the kernel substitute of future version 3.0 of 3d_mec (http://www.imac.unavarra.es/3d_mec).

Slabs is a software for analysing the optical reflectances of multilayer dielectric structures at oblique incidence.
