[s.m]

Hi Dear All,
i am working on three element airfoils. i do my mesh with snappyHexMesh, and my analysis with openFoam.
my pressure contour has a flactuation on leading edge of main element, and the leading edge of flap, why?
i change the scheme, i play with the relaxtion-factors, increase the subdivision in blockMesh to have a better mesh, change the boundary conditions, i also use the Gambit for meshing, i do all of this work but this flactuations don't remove.

what should i do, please give me a little help..
thank you very much
