Chapter 4 Mesh generation and conversion

This chapter describes all topics relating to the creation of meshes in OpenFOAM: section 4.1 gives an overview of the ways a mesh may be described in OpenFOAM; section 4.3 covers the blockMesh utility for generating simple meshes of blocks of hexahedral cells; section 4.4 covers the snappyHexMesh utility for generating complex meshes of hexahedral and split-hexahedral cells automatically from triangulated surface geometries; section 4.5 describes the options available for conversion of a mesh that has been generated by a third-party product into a format that OpenFOAM can read.
