**"Discretization"**(v) The method of dividing more complex geometry into simpler geometry. A discretized model can be manipulated using techniques such as finite element analysis, in which all the simple geometric components of a model are evaluated simultaneously.

In SUTRA, discretization is the process of or result of approximating the physical system (spatially) as an assemblage of discrete elements and (temporally) as a series of discrete time steps. Smaller elements or steps result in finer discretization; larger elements or steps result in coarser discretization.

In kriging, the process of approximating the area of a block by a finite array of points.
