This document is aimed at people new to Computational Fluid Dynamics (CFD). Once all surfaces have been defined, the most expensive solution stage is the grid generation. This stage has a profound influence on the analysis success. The various terms associated with grid generation are defined and the different grid types explained. The advantages and disadvantages of different grid types and indicated. The influence of grid quality on accuracy is outlined. Factors that influence grid quality along with desirable grid structure traits are identified. The relationship between grid, turbulence model and also boundary conditions is considered.
Basic expressions that help quantify grid quality are given. The key aspect of mesh planning is addressed. The document is relevant to users of finite volume, finite difference and finite element programs alike.
