Hey guys. I want to perform series of mesh independence check. The problem is I don't how to begin. Assume I want to obtain the pressure coefficient on an airfoil.
1) Shall I first ignore clustering/stretching on Leading edge and trailing edge? I can't figure out how to perform clustering and doing a mesh independence check. Regarding a certain turbulence model shall I do the clustering till I reach the limits for yplus of a certain turbulence model? (e.g. first: k-epsilon with standard wall function, second: enhanced wall function) What should I do with the rest of the domain? Need I check grid dependency for other areas? (e.g. near the inlet and outlet of the domain) 2)What can I do to lower the mass imbalances? (They are about 3-5 not less than 1 % ) |
