cogli2 (formerly known as cogli1) is a simple tool to visualise configurations of coarse-grained simulations. It is straightforward to use and it has a few features that make it very handy to produce publication-ready figures. It supports its own file format but implementing additional parsers is fairly easy. As of now it is not well documented, but this is something we will improve upon in the near future.

This project has been moved to: https://github.com/fmipp/powerfactory-fmu The FMI++ PowerFactory FMU Export Utility is a stand-alone tool for exporting FMUs for Co-Simulation (FMI Version 1.0 & 2.0) from DIgSILENT PowerFactory models. It is open-source (BSD-like license) and freely available. It is based on code from the FMI++ library and the Boost C++ libraries. The FMI++ PowerFactory FMU Export Utility provides a graphical user interface (new in version v1.0) and - alternatively - Python scripts that generate FMUs from certain PowerFactory models. Additional files (e.g., time series files) and start values for exported variables can be specified. Currently, two types of simulations are supported: In quasi-static steady-state simulations a power system’s evolution with respect to time is captured by a series of load flow snapshots. RMS simulations allow to calculate the time-dependent dynamics of electromechanical models, including control devices (new in version v0.6).

pybrn is a Python package for the analysis of biochemical reaction networks. It provides basic model handling capabilities, import from SBML, analysis of conservation relations, steady state computation and model simulation.

Matlab/Octave implementation of the 2D Rigorous Coupled Wave Analysis

syfluid is a funny toy as well as a real simulation. It simulates a fluid or a gas in a very colorful, graphic and sometimes psychodelic way. In realtime! Drag while your right mouse button is pressed to "draw" the fluid/density field. Drag while your left mouse button is pressed to make the whole thing move, i.e. to "draw" the "forces" that you're adding to the fluid/density field. Press "r" to clear the screen and "m" to open the menu. Press "1" .. "8" to switch color presets. SPACE to pause. "s" to save a png or jpg. syfluid is written in C++ using OpenGL. Even though it is heavily performance optimized and using OpenGL Shading Language (GLSL), it is a performance hog. Use "f" to show the FPS. If they are lower than 30, then reduce the quality parameter that you find in the menu from 200 to e.g. 100. For very fast graphic cards, try 400 and above. This fluid simulation is based on on Jos Stam's paper: http://www.dgp.toronto.edu/people/stam/reality/Research/pdf/GDC03.pdf

RTSS is intended for modeling and simulation of robotic manipulators in the Scilab/Scicos environment. Inspired by the Robotics Toolbox for MATLAB by Peter Corke, RTSS provides many functions that are useful in the field of robotics.

uspice (Micro-SPICE) is a very small simulator for electrical circuits. The primary platform are low-power devices, such as graphing calculators.

vtkModeling-beta.zip: it is an extension of Visualization ToolKit 5.0. Basically it's a collection of deformation algorithms, like laplacian surface editing, moving least square, mass spring system, etc.

xPyder is a PyMOL plugin to analyze and visualize on the 3D structure dynamical cross-correlation matrices (DCCM), linear mutual information (LMI), communication propensities (CP), intra- and inter-molecular interactions (e.g. PSN), and more, to produce highly customizable publication-quality images. xPyder identifies networks (using concepts from graph theory, such as hubs and shortest path searching), compares matrices and focuses the analysis on relevant information by filtering the data using a modular, user-expandable plugin system that takes advantage of structural and dynamical information, contributing to bridge the gap between dynamical and mechanical properties at the molecular level.

Palomino was an unfinished action/combat flight simulator. Air-to-air combat mode was never implemented. However, it does have a land-on-carrier and shoot-SAMs missions. Requires OpenSceneGraph. Optional: SDL, FLTK.

SimNation is a simulation of the politics, environment, population and other variables of any country in the world. Your decisions as the president will determine the future of your people and your land. Can you stand up to 2050?

VLE is a multi-modeling and simulation environment to study complex dynamic systems. VLE is based on the discrete event specification DEVS. and it implements the DSDE formalism (A merge of Dynamic Structure DEVS, DSDEVS, with Parallel DEVS, PDEVS). VLE provides a complete set of C++ libraries, called VFL (VLE Foundation Libraries), to develop DEVS models, to gets results of simulations, to launch simulation on cluster. The models can be developed with the DEVS formalism or with the classical mathematical formalism: Ordinary Differential Equation with Euler, Range-Kutta or QSS integrator, Finite state automaton (FDDEVS, UML State chart, Hybrid Petri net). The VLE environment provides an IDE to develop C++ models, DEVS coupled models. VLE have also three ports to use the VFL with Python, Java and R programming languages.

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。

The introduction of physical layer network coding gives rise to the concept of turning a collision of transmissions on a wireless channel useful. In the idea of physical layer network coding, two synchronized simultaneous packet transmissions are carefully encoded such that the superimposed transmission can be decoded to produce a packet which is identical to the bitwise binary sum of the two transmitted packets. This paper explores the decoding of superimposed transmission resulted by multiple synchronized simultaneous transmissions. We devise a coding scheme that achieves the identification of individual transmission from the synchronized superimposed transmission. A mathematical proof for the existence of such a coding scheme is given.

123panYouthMember is a browser userscript that enhances and modifies the web interface of the 123 Cloud storage service. It can simulate membership-related visual elements while also exposing selected functions that are restricted or hidden by the site's front end. The script includes options for removing advertisements, changing playback speed, and customizing visible account information such as avatars, usernames, and displayed membership levels. Its documentation emphasizes that simulated membership is largely a client-side presentation change and does not grant server-controlled benefits such as additional storage capacity. The project evolved from an earlier download-assistance script and was later extensively restructured. It supports popular userscript-capable browsers and is distributed under the AGPL-3.0 license.
