Dear Alina,rnrnsome years ago we simulated the flow around a falling ball (cf. http://optilb.org/openlb/others 3d falling ball). We got good results for Re=10,100,1000 and 5000 with D3Q19 BGK-Boltzmann model and also for Re=10000 and 100000 with D3Q19 Smago BGK-Boltzmann model.rnrnMaybe your boundary conditions are not right or your resulotion is not fine enough.rnrnBestrnMathias
