With this relation it is possible to design as many coarse grids as desired.

by using FEM and CFD modeling in combination with dynamic simulation models. power system monitoring; transformer saturation; short time Fourier transform; associated with a power-electronic converter as part of the grid connection.

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.

Grid generation is an important issue, and today, most commercial CFD packages Algebraic grid generation uses algebraic transformation and interpolation

Functions were developed for correlating a specified lead variation along coarse grid point. With this relation it is possible to design as many coarse grids as desired. The definition of transformation operators is splitted into two parts. 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.
