Hello,nFirst, I remember you were using 2D model. If you are still using it, all your calculations are for cylinders, not spheres ... nSecond, depending in your turbulence model, the values of the forces at the wall are very sensitive to the mesh size. Your first cell height should be equal to Y+ in case of k-omega and you can increase this by an order of magnitude with k-epsilon. In your case I recommend k-omega as the flow domain is small with no outle and you you will have a transition flow. nThird, As I can see from your above photo that the reference length is 1 [m] ... So this force is for 1 meter long cylinder if you are still using 2D model.n
