GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.

MCX is a GPU-accelerated, general-purpose, physically-accurate and feature-rich 3-D light transport simulator. It is one of the fastest simulators because it can use tens of thousands of GPU threads to simulate photons in parallel.

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.

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.

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.

Knitter produces a 3-dimensional model of a knitting pattern. It supports KnitML, as well as a native language similar to that of traditional knitting patterns.

A C/C++ library for Cavity Quantum Electrodynamics Simulations. CQEDSimulator is a framework that provides all basic mathematical elements and methods to perform quantum numerical simulations. It's crossplatform, that works on Windows, Linux, Mac...

This software accompanies the textbook "Quantum Wells, Wires and Dots" (4th Edition), Paul Harrison and Alex Valavanis, Wiley, Chichester (2015). It is adapted (by the same authors) from code that was originally supplied on a CD with the first edition of the book [1] and is now made available under the GPL3 license. In brief, we encourage everyone to use the software in your studies and research, to study and modify the source-code and to share it widely. However, you are not permitted to include any of our code in a closed-source project.

SLFCFD stands for San Le's Free Computational Fluid Dynamics. It is a package of scientific software and graphical user interfaces for use in computational fluid dynamics. It is written in ANSI C and distributed under the terms of the GNU license.

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/).

VASPMO aims at visualizing wavefunctions (or molecular orbitals) from VASP calculations. It reads VASP's output files PROCAR and CONTCAR, and exports an *.out file in Gaussian's output format, which can be visualized by many popular visualization tools, such as JMol, Molekel, Chemcraft, Gabedit and Molden, etc. These tools can further generate *.cube files, which can be visualized by an even wider range of softwares. 读入VASP计算得到的PROCAR和CONTCAR文件，输出Gaussian结果文件。该文件能够被常用的量子化学可视化软件（如Molekel、Chemcraft、Gabedit、Molden和JMol等）读取，进而绘制和观看体系的分子轨道。有些软件还能导出 cube文件（如Chemcraft和Molden等），从而又能被很多支持cube格式文件的可视化软件所识别。

A 2-D inviscid flow and adjoint solver on unstructured triangular grids. It makes use of a vertex-centroid finite volume scheme which is second order accurate. The adjoint solver is developed using the automatic differentiation tool called TAPENADE. Code has been moved to https://github.com/cpraveen/euler2d

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

Ani2D provides portable libraries for each step in the numerical solution of systems of PDEs with variable tensorial coefficients: (1) unstructured adaptive mesh generation, (2) metric-based mesh adaptation, (3) finite element discretization and interpolation, (4) algebraic solvers.

This project demonstrates the use of a sniper gun (physics), and the behaviour of agents in a 3D world in case of a catastrophy like the assassination of a person.

Blit contains a group of highly efficient iterative sparse solvers that can handle multiple right-hand-sides (i.e. block solvers). We will implement BLQMR, BLGMRES and other block algorithms in MATLAB, FORTRAN 90, C/C++, CUDA and OpenCL.
