This document discusses best practices guidelines for computational fluid dynamics (CFD) modeling. It addresses sources of errors in CFD such as round-off error, iteration error, and discretization error. It emphasizes the importance of mesh quality, resolution, and aspect ratio. Examples are provided to illustrate modeling errors and the impact of poor meshing practices. The document concludes with a discussion of mesh quality metrics and statistics.
