Below is the plot output by AIM for the same situation. As a qualitative comparison, it can been seen that the two plots are similar. There is an area of recirculation in the aneurysm, which is the key feature of aortic aneurysms. Further validation with experimental or other numerical results would be needed to assure the accuracy of the simulation.
