2D airfoil simulation using fluent
 

hey guys I am new to ansys fluent ,
Now am making a 2d airfoil simulation using the KOmegaSST turbulence modele ,
when i started the program i set it to double precision and i set my convergence cteriria to be 1e-6 for all the variables. but once i run the simulation it converges till 2e-6 for velocity pressure k and Omega but for the continuity equation it remains stuck at 2e-5.
Can you help me with that?!!

The continuity residual is scaled different than the others, it's normalized by the worst residual in the 1st 5 iterations. I would ignore the continuity residual altogether and focus on why you can't achieve 1e-06 on the transport variables.

thank you for the answer i'll try to modify the mesh than ill try to re-run the simulation and tell you what i get.
