Mesh generation process has two main phases:

• background mesh generation.
• snappyHexMesh mesh generation:
  • castellate mesh
  • snap mesh
  • add layers

To imagine the meshing process, see the attached video
training/run/snappyTestCase/snappyEvolution.mp4,
which shows all the intermediate steps of snappyHexMesh mesh generation.
