*3.1. Mesh Results*

The final result is a mesh with satisfying values of skewness, orthogonality, and aspect ratio. All these parameters, and many others, widely fit all the quality criteria set by the OpenFOAM standards. An example of structured mesh is presented in Figure 4, which represents the discretization of a SANDEN TRSA09-3658 scroll compressor. Table 2 contains some illustrative values of skewness, non-orthogonality, and aspect ratio for this grid. More details on this machine, which has been numerically analyzed in this work, are given in the next sections of this paper.
