NLR-7301 Ma=0.185 ,angle 6 ,inviscid flow

After deciding the criterion of the refinement eg the mean error of energy ,for subsonic flow at   ,angle of inflow = ,over the two element airfoil ,the new refined mesh is the following:

And the pressure coefficient is the following graph (this is not troll :p)
