Hello guys ,
I am making a 2D airfoil simulation using OpenFoam turbulence modele (k kl omega) once i launche my calculations using pimpleFoam it starts okk but than diverges for the k Kl and Omega . While for the time step continuity Error evrrything is Okk.


1/- is this related to my mesh or it is because of the solver options that i need to Change .
2/- also for my boundary conditions i ve followed those used in the openfoam tutorial in tut/incopressible/pimpleFoam/RAS/elipseKKlomega.
3/-for the kl value i only used a small value of 1e-5 ( is there a way to calculate it or the value i used is okk?)
4/-for the mesh i used it is combined of two types of mesh where i ve used mergemeshes and stitchmesh to get my final mesh thats why you find front1 front 2 back 1 and back2



And these are the boundary conditions i used Are Attached and also the fvSolution and fvSchemes .

Try first solving using k-omega sst, or Spalart Allmaras and set the residuals quite low
