The prolongation is where \(\alpha\) is an adjustable parameter of the transformation \((0<\alpha<1)\) and \(N_2\) is the grid number of the direction. As shown in the following figure, the grids are more clustered towards the both ends as the parameter \(\alpha\) approaches 1. Most techniques for doing computational fluid dynamics rely on the subdivision of space into a grid of discrete volume elements in which average values of flow variables can be defined. The simplest kind of grid is one composed of rectangular elements defined by a set of planes perpendicular to each of the coordinate axes (x,y,z).

The transformation from coarse to fine grids is denoted as interpolation / prolongation and the transformation from fine to coarse grid is called restriction. The prolongation is where \(\alpha\) is an adjustable parameter of the transformation \((0<\alpha<1)\) and \(N_2\) is the grid number of the direction. As shown in the following figure, the grids are more clustered towards the both ends as the parameter \(\alpha\) approaches 1. Most techniques for doing computational fluid dynamics rely on the subdivision of space into a grid of discrete volume elements in which average values of flow variables can be defined.

We interpret the boundary fitted grid as a coordinate transformation from a physical domain to a computational domain . In the computational domain the
