✦ Synopsis

A relation is given between grid properties such as grid angle and aspect ratio and the metric coefficients of the transformation from the physical to the computational domain. A transformation is proposed in which these grid properties occur explicitly, such that the resulting grid will have the required grid angle and aspect ratio. This leads to an elliptic grid-generation procedure with non-linear coefficients. Some examples are given which illustrate that the properties can be predicted.
