How do I check the overall growth rate of my domain? I tried using the polyhedral mesh with min orthogonal quality of 0.19 but the drag coefficient is still far from the experimental value. Decreasing the element size of the mesh seems to not have that much effects as the drag coefficient varies between 0.2 and 0.3 not exceeding this value. my mesh and setup are as below:
