Taskin Guest Posts: n/a	hi, I have been making a 3D flow analysis. Although my geometry is not very complex, I couldn't form a boundary layer on the faces of the geometry. Also the analsys results are slightly below the real results, drag ceoffiient should be 0.6 but Fluent calculates it like 0.43. I wonder could this difference caused by the lack of boundary layer in my mesh? Thanks, Taskin
