I'm studying 2D steady incompressible flow over NACA 0012 airfoil (Re = 6*10^6 , M<0.3). I have used simpleFoam solver with K-epsilon turbulence model but in this way no laminar zone appears.
I need to resolve transition from laminar to turbulence but i don't know like. If OpenFoam doesn't resolve transition, it is at least possible to fix the transition-point on airfoil?(In fact i know this point from XFoil)
