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. The CFD Simulation Process : Grid generation or meshing is a very critical part within the CFD simulation process as it not only dictates the simulation time but also the accuracy of results of the study. Generating a very coarse and poor quality mesh/ grid often leads to non-physical or highly inaccurate simulation results though may be solved on a very powerful solver. •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.
