ABSTRACT
The simulation describes the field of study concerned with the use of a computer to duplicate the behavior of a system. Simulation inevitably involves the study of the activities of a particular system. The system of interest have actual physical analogue, such as electric power plant, or it may be completely hypothetical, such as a simulation which models an airfoil whose geometry is known, but has not yet been built. In either case, the purpose of a simulation is to make useful conjectures regarding the model which are applicable to the system itself, without having to manipulate or observe the actual system. Bringing the power of a computer to bear upon any problem of simulation is a logical extension of any modeling methodology. Simplification of the system to be analyzed is necessary because there is always a finite pool of resources (like time, computing power, or money) available to commit to the simulation.
