Modelling and simulation

Print
Back

Computers are excellent tools for testing ideas, manipulating large amounts of data and answering ‘what if…’ questions.

The difference between a model and a simulation is in the form of the output. Modelling usually deals with numerical outputs, eg with a spreadsheet model you could use formulae and functions to calculate the stresses on a bridge. A simulation might try to physically represent this by showing a graphic of how the bridge breaks as a truck passes over it.
