bye bye my blue is an unknown quantity at this point
'm simulating 2D airfoil..

Governing eqn is kEpsilon

y+ min : 6.96 max = 30.79859 average = 15.6028

and mesh is generated by salome (viscous layer =0.03 and distance:0.0006)

at (http://www.pointwise.com/yplus/), i used 0.0006


xfoil naca0015 Cd = 0.00579 and mine is 0.048

I don't know what is the problem..

here are mesh picture and 0,system,postprocess folders

Thanks
