Canonical flows 1 | openfoam: boundary layer, inflation layers, meshing
Description:
In this video I go over some boundary layer theory and why inflation layers are important. This is done by setting up a boundary layer case in openfoam where the mesh is the inflation layers above a flat plate. This case has been set-up to explore the boundary layer “canonical flow”. I show you

how to compute inflation layer parameters (number of cells, growth ratio, first cell height) from initial conditions (velocity, kinematic viscosity, skin friction coefficient, etc..) and desired y+ (yplus) and provide a python code for this.
