My goal is to reach the known drag coefficient an drag force values for the sphere just to get some validation for a more complicated simulation i am working on. But actually the solutions i get in my fluent simulations are very different then what i found in the literature. I chose the k-omega SST viscous model for the simulation. I did also set the reference values and generated a fine mesh.&nbsp;<\/p>\n<p><\/p>\n<p>I created a little table with the values i got from my simulation and the literature i found.<\/p>\n<p><\/p>\n<p>Does anyone know where the problem might be or what i am doing wrong ?
