Implementation of LES, law of the wall and log law inflow in OpenFOAM
The input case file buildingLES can simulate flow around a cube using LES turbulence model with logarithmic inflow profile and law of the wall boundary condition. The ASEE-LES.pdf has the detail of how to run the case file using OpenFOAM.
Executing the case file:
To run the simulation, the following commands should be executed under the buildingLES directory:
• Generate hexahedral multi-block mesh
$ blockMesh
• Run the simulation
$ pisoFoam
