Real time simulation


Can anyone tell me, what is real time simulation and why it must be used?

Thank you

RE: Real time simulation

It's simulation that is at the same rate as reality would be. This, as compared to high speed simulation.

An example of non-realtime would be an astrophysicist who uses a computer simulation to model two stars colliding. They would run the simulation as fast as they can and watch it all occur in a minute or two whereas reality is going to take millions of years.

A realtime example is the Alaskan pipe line. A realtime simulation of the flow is continually running so if 'reality' changes it will be detected and the line can be shut down. A reality change would be a pin hole leak developing somewhere that would cause the actual conditions to change from the predicted simulation.

RE: Real time simulation

A real-time simulation might be something done on this http://www.dspace.com/en/inc/home/products/hw/sing... which allows one to run Matlab/Simulink code fast enough to operate hardware in real-time, i.e., hardware-in-the-loop (HIL) simulation.

Often, real-time systems have peripheral events that can affect system performance that cannot be modeled accurately in a simulation, such as resource contention and interrupt service.
