Web-based Modeling and Simulation

Web-based M&S is the one where the M&S application is accessed over a network by using the HTTP protocol for communication between the client computer and the M&S application running on a server computer.

Gas Cloud Simulation

A simulation of how a gas cloud that has been observed approaching the supermassive black hole at the centre of the galaxy.

Advanced Test Reactor Simulation

Advanced simulation capabilities can model reactors, such as INL's Advanced Test Reactor shown here, from atomic scales to full-sized reactor assemblies.

Underwater EVA Simulation

Underwater simulation of extravehicular activity (EVA).

Combat Simulation

A screen capture depicts a combat situation in a digital world during a command post exercise inside the Joint Multinational Simulations Center.

Motorcycle Simulator

Testing motorcycle simulator at the Pentagon to get a feel for how the bike would handle some situations.

Wake Turbulence Simulation

Wake turbulence simulation for an Airbus A340 on final approach, just before touchdown.

Driving Conditions Simulator

View from the cockpit of the simulator. Multiple screens provide a view similar to what one would see in a snowplow on the road.

Molecules Simulation

Dynamic computer simulations of molecular systems.

Global Aerosols Simulation

This portrait of global aerosols was produced by a Goddard Earth Observing System Model, Version 5 (GEOS-5) simulation at a 10-kilometer resolution.

Driving Simulation

Simulation for driving training.

Web-based Modeling and Simulation



    • A Network-Centric M&S application is the one, the components of which run on different server computers and communicate over a network (e.g., Internet, virtual private network, wireless network) using the TCP/IP, HTTP, RMI or another protocol.

    • The server computers running the models or model components of a network-centric M&S application can be geographically dispersed or be part of a local area network.

    • A Web-based M&S application is a network-centric M&S application, which uses the HyperText Transfer Protocol (HTTP) for the communication among its components over a network.

    • Users use client computers to access or interact with the M&S application running on server computer(s).

    • Client-Server Architecture and Service-Oriented Architecture are popular ones for building network-centric M&S applications.

    • Java Platform, Enterprise Edition (Java EE) and Microsoft .NET Framework are two industry standard platforms for building network-centric M&S applications.

Intended Uses / Objectives

    • Enable geographically-dispersed users to use the M&S application over a network
