Numerical simulation consists in representing a physical system by a
mathematical model whose equations can be solved with help of modern computing.
Virtual (or "numerical") experiments are then performed to provide accurate
views of the physical system evolution under various conditions.
Numerical simulation is used to complement real (and expensive)
experiments by computer calculations which provide exhaustive information at
a low cost. Since numerical simulations provide an image of the real
process, the effect of any kind of process change (geometry, materials,
operating conditions) on the product quality is easily investigated by this
technique. |
