While qualitatively similar, the numerical results are significantly different than those found in the validation. By refining the mesh, the results can be calculated to a more accurate degree. Go back to the Mesh task in the workflow and increase the Mesh resolution all the way up. Go back to the Results and press Evaluate Results. Travel back to the Pressure contour.
These results compare more favorably to the FLUENT results, though they are still significantly different. However, the mesh in the FLUENT study was much more refined than the one used here, especially in the critical wake region immediately behind the Ahmed body. Additional refinement of the AIM mesh would further improve the results and is recommended practice for external flow around vehicles.
