The Free On-line Dictionary of Computing (30 December 2018):

simulation
simulate

    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.

   See also emulation, Markov chain.
