simulation sim·u·la·tion (sĭm’yə-lā’shən)

Close resemblance or imitation, as of one symptom or disease by another.

Assumption of a false appearance.

Reproduction or representation, as of a potential situation or in experimental testing.

sim’u·late’ (-lāt’) v.
sim’u·la’tor (-lā’tər) n.
simulation, system
Attempting to predict aspects of the behaviour of some system by creating an approximate (mathematical) model of it. This can be done by physical modelling, by writing a special-purpose computer program or using a more general simulation package, probably still aimed at a particular kind of simulation (e.g. structural engineering, fluid flow). Typical examples are aircraft flight simlators or electronic circuit simulators. A great many simulation languages exist, e.g. Simula.
