Real AAA 3D models were created by three-dimensional (3D) reconstruction of in vivo acquired computed tomography (CT) images from 5 patients. Based on 3D AAA models, high quality volume meshes were created using an optimal tetrahedral aspect ratio for the whole domain. In order to quantify the WSS and the recirculation inside the AAA, a 3D CFD using finite elements analysis was used. The CFD computation was performed assuming that the arterial wall is rigid and the blood is considered a homogeneous Newtonian fluid with a density of 1050\u2009kg\/m<jats:sup>3<\/jats:sup>and a kinematic viscosity of<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mn fontstyle=\"italic\">4<\/mml:mn><mml:mo>\u00d7<\/mml:mo><mml:msup><mml:mrow><mml:mn>10<\/mml:mn><\/mml:mrow><mml:mrow><mml:mo>-<\/mml:mo><mml:mn fontstyle=\"italic\">3<\/mml:mn><\/mml:mrow><\/mml:msup><\/mml:math>Pa\u00b7s.
