Using a mesh that is 20x20x200 is not fine enough to represent the flow patterns around a vehicle . This is why refinements existso refinements will be added around the car. Locate the Refinements section in the navigation panel, and begin by adding a bounding box refinement. Change the Face to Ymin, Min thickness to 0 m, and Final thickness to 12e-3 m. Save the refinement by clicking the blue check mark in the top right of that panel. Add a region refinement. Change the Refinement mode to Distance and use values similar to those from Table 2.1. These values can vary depending on how many elements you want in your mesh.
