Let's extend the chapter of the »Rock Vapor Classic« training series with the snapping procedure of the application snappyHexMesh. During the training video, one will get an idea of the different parameters we can choose in the »snapControl« sub-dictionary in the snappyHexMeshDict file. Furthermore, even though the parameters one can set in the snapping control are manageable, the whole procedure is more complex. You are welcomed to watch the whole video as there are a few hints and tips and tricks to resolve different errors and problems.

Content of the training video:
00:00   Introduction
02:04   Explaining what snapping means
07:00   Creation of the first snapped mesh and the influence of the parameter »tolerance«
12:40   Resetting the »tolerance« parameter and recreating the mesh
14:30   Explaining »feature Snapping«

19:05   Influence of nFeatureSnapIter parameter
25:00   Details about nSolveIter
31:40   Details about nRelaxIter

33:30   Details about nSmoothPatch and nonOrthogonality
43:50   Further information regarding the control parameters (Engys PDF)
46:00   Analysis of the mesh in general and optimization suggestions


Sorry for the - again - long training video but I could not shorten it. Furthermore, as you can see, snappyHexMesh is a big tool and the meshing process is highly complex.
