Mash is on a distinguished road
hey there, Im a bit of a newby to Openfoam, struggling to validate my results for Naca 0012 at 10deg angle of attack.
im not sure if it's a meshing or BC issue but looking at the velocity profile of the wake it seems way off.
any help will be much appreciated!!
primaraly interstead in the tip vortex
Code:
FoamFile

Quick note: Part of the answer to this thread (regarding k-omega initialization) is being dealt on another thread: k and omega at inlet for k-omega SST
