CFD Analysis of a Smoking Pipe | Part 7 | SnappyHexMesh Layer Generation ∇ OpenFOAM® v8
Channel: Holzmann CFD
Date: 2021-01-16

A short description of »how to add layers using snappyHexMesh« is presented in the following video and how the algorithm is actually working. Only the main keywords one can set in the control sub-dictionary in the snappyHexMeshDict file are explained as the influence of different parameters are well explained in the already mentioned »comprehensive tour of snappyHexMesh« (an ENGYS PDF one can download on the openfoamwiki.net).


The topics we are going through are the following:

00:00    Introduction
03:00   Activating the layer generation algorithm
03:55   The »addLayersControls« dictionary
04:15   The »relativeSize« description
05:30   The »layers« sub-directory and the control settings
10:30   Extended options for layer-set-up and definitions
14:52   First layer generation and visualization (including explanation)
19:40   How does snappyHexMesh add layers (algorithm idea)

21:21   Other meshing examples with different layer-parameters



Sorry for my haircut but I want to be as natural as I can be .) 
Keep foaming and healty,
