BoundaryLayer setup for Gmsh 3D meshing

copyright (C) 2011-2017 iesensor.com

Precise control of the thickness of the first cell normal to wall, is crucial for  turbulence models like k-epsilon, k-omega. Before moving to turbulence flow simulation for CFD workbench of FreeCAD

2D meshing with boundary layer, tutorial

3D boundary meshing for simple cube is also done, based on FreeCAD FEM workbench example of 3D cantilever.
CAD and Gmsh setup files are embeded.
photo and progress will be updated on the FreeCAD Fem post
