5.4.1 The mesh generation process of snappyHexMesh. The process of generating a mesh using snappyHexMesh will be described using the schematic in Figure 5.8 . The objective is to mesh a rectangular shaped region (shaded grey in the figure) surrounding an object described by a tri-surface, e.g. typical for an external aerodynamics simulation.

Mesh sizes are defined as relative to the starting background mesh. For example, if the background mesh size is 0.2 m, the mesh sizes at one and two levels of refinement will be 0.1 m and 0.05 m respectively. refinement is performed by cutting cells in half in each direction, i.e. a 3-D cell is transformed into 8 cells..
