The solution accuracy of any model using computational fluid dynamics is dependent upon the quality of the discretised mesh. This report details the range of spatial and flow properties affecting the accuracy and stability of any solution and comments upon their individual effects. Methods of calculating these properties upon an arbitrary 3D mesh are defined and statistical analysis provides a unique quantative value upon any given mesh. As a result volumes of poor grid quality can be identified without user interpretation, as well as the most suitable form of rectification.
