3.3.1
idealization

representation of one thing by another thing that in a particular context is both simpler than, and an approximation to, the first thing

EXAMPLE 1   In the context of a numerical calculation, the numbers 3, 22/7, 355/113, and 3,14159265 are all idealisations of the mathematical constant pi, in increasing order of reality.

EXAMPLE 2   In the context of a finite element analysis, a mesh of elements is an idealisation of the shape of the thing being analysed.
