A longitudinal study of a lateral intracranial aneurysm: identifying the hemodynamic parameters behind its inception and growth using computational fluid dynamics

A numerical investigation of the mechanics of intracranial aneurysms walls: Assessing the influence of tissue hyperelastic laws and heterogeneous properties on the stress and stretch fields

“…For the type of fluid meshes used in this work, mesh-sensitivity studies were carried out extensively with different IAs geometries and were not included here. They yielded a volume density of cells in the range of 3000 to 4000 cells/mm 3 (an example of this study can be found in Oliveira et al [58]). This level of refinement was assured for the meshes used in this work.…”

“…For each patient-specific IA geometry, these regions were identified after performing CFD simulations using the rigid-wall assumption -the specific methodology of these simulations can be found elsewhere [58]. The TAWSS and OSI were computed and the identification of the abnormal-hemodynamics patches was performed automatically by using an in-house code implemented with the VTK ® library (see Fig.…”
