Web-based simulation
open-in-new
<h2 id="application">Application</h2> <p>Web-based simulation is used in several contexts: </p> <ul><li>In <a href="/facts/E-learning/5lf2A2Vj">e-learning</a>, various principles can quickly be illustrated to students by means of interactive <a href="/facts/Computer_animation/rPW63nm0">computer animations</a>, for example during lecture demonstrations and computer exercises.</li> <li>In <a href="/facts/Distance_learning/73oPr8FW">distance learning</a>, web-based simulation may provide an alternative to installing expensive simulation software on the student computer, or an alternative to expensive laboratory equipment.</li> <li>In <a href="/facts/Software_engineering/KX6cE9kz">software engineering</a>, web-based emulation allows application development and testing on one platform for other target platforms, for example for various <a href="/facts/Mobile_operating_system/wysBVca1">mobile operating systems</a><a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> or <a href="/facts/Mobile_web_browser/tKvf0bfJ">mobile web browsers</a>, without the need of target hardware or locally installed <a href="/facts/Emulator/FMHE8qDj">emulation software</a>.</li> <li>In <a href="/facts/Online_computer_game/UH6ItLnW">online computer games</a>, 3D environments can be simulated, and old <a href="/facts/Home_computer/CDEPVd1T">home computers</a> and <a href="/facts/Video_game_console/K72D1NSS">video game consoles</a> can be emulated, allowing the user to play old computer games in the web browser.</li> <li>In <a href="/facts/Medical_education/yzs4WxGr">medical education</a>, <a href="/facts/Nurse_education/Vrk762Fo">nurse education</a> and allied health education (like <a href="/facts/Sonographer/5UWl3BBl">sonographer</a> training), web-based simulations can be used for learning and practicing clinical healthcare procedures. Web-based procedural simulations emphasize the cognitive elements such as the steps of the procedure, the decisions, the tools/devices to be used, and the correct anatomical location.</li></ul> <h2 id="client-side-vs-server-side-approaches">Client-side vs server-side approaches</h2> <p>Web-based simulation can take place either on the server side or on the client side. In <i>server-side simulation</i>, the numerical calculations and <a href="/facts/Visualization_(computer_graphics)/xVfxo6FJ">visualization</a> (generation of plots and other computer graphics) is carried out on the web server, while the interactive <a href="/facts/Graphical_user_interface/wBlQFWDP">graphical user interface</a> (GUI) often partly is provided by the client-side, for example using <a href="/facts/Server-side_scripting/JnLx8FnL">server-side scripting</a> such as <a href="/facts/PHP/vU6YRJX0">PHP</a> or <a href="/facts/CGI_script/zWsLFXGJ">CGI scripts</a>, interactive services based on <a href="/facts/Ajax_(programming)/cS0P0whT">Ajax</a> or a conventional application software remotely accessed through a <a href="/facts/VNC/xTmWVgV4">VNC</a> Java applet. </p><p>In <i>client-side simulation</i>, the simulation program is downloaded from the server side but completely executed on the client side, for example using <a href="/facts/Java_applets/oulP2dyy">Java applets</a>, <a href="/facts/Flash_animation/NkgqK5Ja">Flash animations</a>, <a href="/facts/JavaScript/XhhIIEsl">JavaScript</a>, or some mathematical software viewer plug-in. Server-side simulation is not scalable for many simultaneous users, but places fewer demands on the user computer performance and web-browser plug-ins than client-side simulation. </p><p>The term on-line simulation sometimes refers to server-side web-based simulation, sometimes to <a href="/facts/Symbiotic/MrBArRGa">symbiotic</a> simulation, i.e. a simulation that interacts in real-time with a physical system. </p><p>The upcoming <a href="/facts/Cloud_computing/guhg0FGV">cloud-computing</a> technologies can be used for new server-side simulation approaches. For instance, there are[<i>example needed</i>] <a href="/facts/Multi-agent_simulation/C3C1vR8s">multi-agent-simulation</a> applications which are deployed on cloud-computing instances and act independently. This allows simulations to be highly scalable. </p> <h2 id="existing-tools">Existing tools</h2> <ul><li><a href="/facts/AgentSheets/kYeIbWLQ">AgentSheets</a> – graphically programmed tool for creating web-based <i><a href="/facts/The_Sims/BkN45HoU">The Sims</a></i>-like simulation games, and for teaching beginner students programming.</li> <li><a href="/facts/AnyLogic/CHfWmTkn">AnyLogic</a> – a graphically programmed tool that generates Java code for <a href="/facts/Discrete-event_simulation/gQjkaft8">discrete-event simulation</a>, <a href="/facts/System_dynamics/EPI2wWsI">system dynamics</a> and <a href="/facts/Agent-based_model/C3C1vR8s">agent-based models</a></li> <li><a href="/facts/Easy_Java_Simulations/Jl8hFywA">Easy Java Simulations</a> – a tool for modelling and visualization of physical phenomenons, that automatically generates Java code from mathematical expressions.</li> <li><a href="/facts/ExploreLearning/aKDqfyLr">ExploreLearning</a> Gizmos – a large library of interactive online simulations for math and science education in grades 3–12.</li> <li><a href="/facts/FreeFem%252B%252B/7mWU3VHA">FreeFem++</a> Javascript Version<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> – FreeFem++<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> is a free and open source PDE solver using the finite element method.</li> <li><a href="/facts/GNU_Octave/vVVq5evM">GNU Octave web interfaces</a> – <a href="/facts/MATLAB/qPjLISCk">MATLAB</a> compatible open-source software</li> <li><a href="/facts/Lanner_Group_Ltd/UwGvo8e7">Lanner Group Ltd</a> L-SIM Server – Java-based <a href="/facts/Discrete-event_simulation/gQjkaft8">discrete-event simulation</a> engine which supports model standards such as <a href="/facts/BPMN/JQ1w8eWJ">BPMN</a> 2.0</li> <li><a href="/facts/Nanohub/xarF5ptQ">Nanohub</a> – web 2.0 in-browser interactive simulation of <a href="/facts/Nanotechnology/Co4FFNfY">nanotechnology</a></li> <li><a href="/facts/NetLogo/3pzyYsKH">NetLogo</a> – a multi-agent programming language and integrated modeling environment that runs on the Java Virtual Machine</li> <li><a href="/facts/OpenPlaG/DBmyM9t0">OpenPlaG</a> – <a href="/facts/PHP/vU6YRJX0">PHP</a>-based function graph plotter for the use on websites</li> <li><a href="/facts/OpenEpi/l1qGQnJ6">OpenEpi</a> – web-based packet of tools for <a href="/facts/Biostatistics/Sv5s38Kh">biostatistics</a></li> <li><a href="/facts/Recursive_Porous_Agent_Simulation_Toolkit/DKD7YS3D">Recursive Porous Agent Simulation Toolkit</a> (Repast) – agent-based modeling and simulation toolkit implemented in Java and many other languages</li> <li><a href="/facts/SageMath/5mzh5TlB">SageMath</a> – open-source numerical-analysis software with web interface, based on the <a href="/facts/Python_(programming_language)/YbuGqofa">Python programming language</a></li> <li><a href="/facts/SimScale/nwYeBa30">SimScale</a> – web-based simulation platform supporting <a href="/facts/Computational_fluid_dynamics/zuWdtNJp">computational fluid dynamics</a>, <a href="/facts/Solid_mechanics/e1Yq50IS">solid mechanics</a>, and <a href="/facts/Thermodynamics/q4hIx3yP">thermodynamics</a></li> <li><a href="/facts/StarLogo/MYRNycXd">StarLogo</a> – agent-based simulation language written in Java.</li> <li><a href="/facts/VisSim/vIN12QVm">VisSim viewer</a> – graphically programmed <a href="/facts/Data-flow_diagram/kAJMEeJc">data-flow diagrams</a> for simulation of <a href="/facts/Dynamical_systems/782gREl5">dynamical systems</a></li> <li><a href="/facts/Mathematica/dRwoGFG2">webMathematica and Mathematica Player</a> – a computer algebra system and programming language.</li> <li><a href="/facts/VisualSim_Architect/c7J8n6F7">VisualSim Architect</a> – VisualSim Explorer enables system-level models to be embedded in documents for viewing, simulation and analysis from within a web browser without any local software installation.</li></ul> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/List_of_online_spreadsheets/0cvc1GeB">List of online spreadsheets</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="http://vam.anest.ufl.edu/wip.html">A portfolio of public-access and free web-based simulations</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Byrne, James; Heavey, Cathal; Byrne, P.J.
