OpenRocket is a free and fully featured simulation software for designing, analyzing, and optimizing model rockets before physical construction and launch. It provides a comprehensive environment where users can assemble rocket components, visualize designs in both 2D and 3D, and simulate flight behavior using accurate aerodynamic and physics models. The software incorporates six-degree-of-freedom flight simulation, allowing it to model real-world dynamics such as stability, drag, thrust, and staging effects. Users can analyze simulation outputs like altitude, velocity, and acceleration through detailed plots, enabling iterative improvements to rocket designs. OpenRocket also supports exporting designs for manufacturing processes such as 3D printing or laser cutting, bridging the gap between simulation and real-world prototyping.

DLD V 2.0 Released Digital Logic Design is a Software tool for designing and simulating digital circuits. It provides digital parts ranging from simple gates to Arithmetic Logic Unit. You may start your circuit from simple gates and flipflops and keep on converting them into ICs. These ICs, later on, may be incorporated into other circuits to built more complex circuits like CPU. You may even use SOP expressions to generate digital circuits in IC form. You can use this software to design Combinational, Synchronous and Asynchronous Sequential Circuits. The circuit working can be analyzed by using output parts like LEDs, Seven Segment Display as well as CRT and digital Oscilloscope all provided in the software. This Software may be used by professionals, hobbyists and students alike. The teachers may incorporate this software in their courses like Digital Logic and Computer Design, Computer Architecture, Computer Organization and Embedded Systems.

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.

Software for sustainability assessment, highly modular; initially focused on Life Cycle Assessments.

JMCAD is an program for the modeling and simulation of complex dynamic systems. This includes the ability to construct and simulate block diagrams. The visual block diagram interface offers a simple method for constructing, modifying and maintaining complex system models. The simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs. With JMCAD, users can quickly develop software or "virtual" prototypes of systems or processes to demonstrate their behavior prior to building physical prototypes. The user builds his system model by selecting predefined blocks from a block library and simply wiring the blocks together. Each block of the diagram performs a function. Users can also create custom blocks in Java and add them to the JMCAD block library. JMCAD is a block diagram language for creating complex nonlinear dynamic systems.

Impact is an explicit Finite Element Program Suite which simulates dynamic impact events. It has a range of elements, contact handling and different material laws. Models can be created, solved and analyzed with the included pre- and postprocessor. Impact is based on an Explicit Time stepping algorithm. These kind of codes are used to simulate dynamic phenomena such as car crashes and similar, usually involving large deformations.

JBioFramework (JBF) is a set of two different chemical separations simulations (2D Electrophoresis and Mass Spectrometry) that are frequently used in chemistry, biochemistry and proteomics research. It is written in the Java programming language and will run on any and all systems that have the JVM installed. As we continue to develop the software over the coming months/years and attempt to quantify the success of our efforts with testing and reviews, user input is very important. Please don't hesitate to review the software below or email Paul Craig [pac8612@rit.edu] with larger descriptions/bugs/feature ideas. Our next scheduled release will contain (in addition to 2DE and MassSpec) a 1D Electrophoresis simulation as well as a tab containing ChemAxon's MarvinSketch [http://www.chemaxon.com/products/marvin/] along with some improved functionality. It should be out shortly as we complete the creation and modification of a permanent domain for the project.

PeerSim is a simulation environment for P2P protocols in java. Its features include easy configuration, extendability and high performance.

Parametric analysis is often needed for exploring design options, especially when a global optimization method is not available, or the optimization result is in doubt. Parametric analysis can also be applied to all design variables simultaneously, which forms an exhaustive search that, providing that the search grid is fine enough, will guarantee a global optimum solution. In order to perform complex parametric analyses on multiple parameters with more than a handful of alternative values each, a tool to generate commands for the simulation model to run, and to collect results afterwards will be needed. jEPlus has been developed as such a parametric tool for EnergyPlus. To see jEPlus in action, check out this video: http://youtu.be/jBA7Q7npNK4 The source code of the jEPlus project is now hosted on GitHub: https://github.com/jeplus/jEPlus/

Visual Figaro is an integrated environment to develop component libraries for the dependability modeling tool KB3 used by EDF (http://www.edf.fr/recherche/codes-de-calcul/kb3). KB3 is based on the FIGARO reliability modeling language, suitable for describing CTMC (continuous time Markov chains), DES (discrete event simulation) models, and for automatic generation of fault trees. FIGARO is objet oriented, close to natural language and enables building libraries of reusable components (knowledge bases). Go to "Files" tab to download various Figaro based tools (Visual Figaro, KB3, YAMS), lots of examples and documentation.
