Discrete Modeling and Simulation

Discrete M&S is the one which uses a model built in terms of logic and the simulation time is represented as a discrete variable. Discrete M&S is typically used in disciplines such as computer science, systems engineering, industrial engineering, operations research, business, civil engineering, and management science. This type of M&S is commonly refered to as Discrete Event Simulation.

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.
