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.

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.

PUPIL (Program for User Package Interface and Linking), is a software environment that allows developers to link quickly and efficiently together multiple pieces of software in a fully automated multi-scale simulation. More specifically, it supports QM/MM MD simulations where the user might choose among any of the different MD engines and QM engines, which are connected to PUPIL as external programs through a tiny specific interface. One of the main advantages here is that the user can use most of the functionalities that may have those external programs interfaced without the necessity to be reimplemented again on independent interfaces. In fact, this simulation interface concentrates all the common code involved in the coupling terms of the QM/MM approach.

Multibody dynamics simulation package with frictional contact and collision detection

This program allows you to create a transmission hologram using just a computer, a laser-printer, and an overhead transparency. This hologram will behave like one created using a laser and can be projected or viewed with a point source.

This project has the role of simulating simple Curvilinear and Rectilinear Motions with an easy to use user interface. This program can be used for educational purposes as well as for any other purpose anyone would like. The executable file is a .jar files which means that it can run in any operating system that supports java. Above you can see a screenshot of the program while it is operating.

FDTD Antenna Simulator is a complete software package for antenna analysis and design using the FDTD method.

Interactive Web Physics is a Java, Web-based animation and problem designer tool. Anyone can quickly design mathematics or physics animations and simulations that run in a web browser. Unlike other solutions, no knowledge of programming is required.

JCreme is an automated interface to the CREME96 modeling web app (https://creme96.nrl.navy.mil/). It allows the user to send multiple requests to the CREME96 website and retrieve the results. CREME stands for "Cosmic Ray Effects on Micro Electronics"

A self-sufficient java framework for numerical solution of ODEs (diff eqs) and visualization. Samples are aeronautics/astronautics/physics/rocketry themed. Focus on clean design, modularity, reusability and documentation. Educational project.

jSGP is a Java implementation of the five SGP/SDP propagators described in NORAD's Spacetrack Report No. 3.

PCP-net is a browser-based application to calculate preheating temperature, heat input and carbon equivalent, which can be used to avoid hydrogen cracking (cold cracking) in unalloyed and low-alloyed ferritic steels.

A Java library that works with Java3D to simulate and visualize, in real-time, dynamics of multiple rigid bodies that are restricted by implicit and explicit constraints (e.g., robotics); designed for efficiency, ease-of-use, and extensibility.

VOpR - A Virtual Optical Rail VOpR allows to create and evaluate simple optical systems, in which the basic optical elements are arranged along the optical axis. The current supported optical elements are: spaces,spherical lenses, circular apertures and flat blocks of some optical medium. The program has three main components: 1. The database editor. Currently the database can store data about: -optical materials, -spherical lenses, -projection properties of light sensors and eyes, -special wavelengths of light and -optical systems as lists of basic optical elements. 2. The editor of linear optical systems. Some properties of the optical system are calculated in real time. 3. The virtual optical rail as a ray-tracing simulation of the optical system. The goal is to provide fast and useful diagnostic images, not realistic blur. Additionally there is full access to the java source code under the terms of the GPLv3.

The Vehicle Maneuver Simulator lets you simulate the maneuvering of simple and complex vehicles with different numbers of wheels, axles and joints.

Virtual interactive experiments (vexp) is a framework to promote the developmentand use of cooperative e-learning experiments over the internet. Interactive scientific experiments which can be controlled by various users synchronously.

To create, as a community, an open-source, GPL-licensed positioning system designed with a service-oriented architecture (SOA) that will run on all major platforms to provide low-cost positioning of any Wi-Fi enabled devices.

DIFFR is a menu-driven graphical software whereby the problem of a plane wave diffraction on a rough surface can be solved using several numerical and approximate methods.

jQuantum is a Java program to simulate a quantum computer, to design quantum circuits, and to visualize the execution of quantum algorithms. Another main purpose, however, is to create images in your head, and thereby - understanding.

A 3-d Constraint-based multibody physics engine written in entirely Java, aimed at real-time capabilities. The user can model bodies, geometries, joints, and parameters. See http://code.google.com/p/jinngine/ for source code and development information.

The mechSym toolkit is a set of classes that support modelling classical mechanics systems with particular interset in robotic designs. Classes simulate sensors, motors, mechanical linkages, and power. visual time-elapsed simulations provided.

AcMus is a project on musical acoustics devoted to the development of models and computer tools for the study of room acoustics and focus on helping the investigation of issues related to the design, control and acoustic treatment of environments. AcMus has not been maintained for a few years now, but the code may still be useful. We consider the current repository to be at https://gitlab.com/ccsl-usp/acmus .

The Gecko Hamaker open-source software project is a full implementation of the fully retarded Lifshitz formulations for isotropic and anisotropic plane-plane and cylinder-cylinder interactions with intervening interlayer materials, planar systems of up to 99 layers, and graded interfaces for the modeling of grain boundaries or other continuously changing systems, accompanied by a database of material optical properties spectra. The machine-readable optical property database is available for download and as a web service and makes available the full spectral optical properties of over 150 materials from both ab initio calculations and experimental measurements.
