Dear all
I always obtain a difference (small or not so small) in my results when I run a problem in grids of different cell sizes. My question is; is there an accepted criteria for rejecting a result in CFD based on such difference?. I mean what's an acceptable size of such difference? I'm starting to work in turbulence (k-e) and the difference in my results in grids with 10000 and 70000 cells can be as big as 30%, is there any remedy? I would thank some reference(s). Thanks Newbie |
