Most students have dealt with polar and spherical coordinate systems. In these notes, we want to extend this notion Almost 50% of the CFD simulation time of any CFD engineer is involved into meshing or mesh generation and hence it is a critical part of the CFD simulation process that needs thorough understanding of the meshing/ grid generation steps.

Numerical grid generation is the crucial initial step involved in computing numerical solutions to the equations that describe a physical process. Abstract The grid generation issues found in the 3D simulation of two-phase flow in a pipe using Computational Fluid Dynamics (CFD) are discussed in this paper. Customized grid generation of twin screw machines for CFD analysis is widely used by the refrigeration and air-conditioning industry today, but is currently not suitable for topologies such as An algebraic grid generation method was used for deforming grid generation of variable lead and varying profile rotors. 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.

•Grid generation is the process of determining the coordinate transformation that maps the body-fitted non- uniform non-orthogonal physical space x,y,z,t into the transformed uniform orthogonal computational spacetransformed uniform orthogonal computational space, ξ,η,ζ,τ. If you want to solve a problem on an arbitrary, non-uniform grid, the physical domain needs to be transformed into the uniform computational domain.

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.
