This work aims to model the physical behavior of real abdominal aorta tracts with and without AAA (Abdominal Aortic Aneurysm), through fluid-dynamic, structural and fluid-structural (FSI) numerical simulations. The geometries are realized starting from CAT (Computed Axial Tomography) scans of real patients, using the meshLab tool for surface optimization, smoothing and the definition of the geometry patches of fluid and solid regions. The resulting geometries are meshed by using the tool cartesianMesh provided by the library cfMesh. For numerical simulations, the finite-volume software OpenFOAM-Extended 4.0 and the external toolbox solids4Foam, which implements structural and fluid-structural models, are used.

Abstract
This work aims to model the physical behavior of real abdominal aorta tracts with and without AAA (Abdominal Aortic Aneurysm), through fluid-dynamic, structural and fluid-structural (FSI) numerical simulations. The geometries are realized starting from CAT (Computed Axial Tomography) scans of real patients, using the meshLab tool for surface optimization, smoothing and the definition of the geometry patches of fluid and solid regions. The resulting geometries are meshed by using the tool cartesianMesh provided by the library cfMesh. For numerical simulations, the finite-volume software OpenFOAM-Extended 4.0 and the external toolbox solids4Foam, which implements structural and fluid-structural models, are used.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
