Abstract
dc.description.abstract
Computational Structural Dynamics (CSD) simulations, Computational Fluid Dynamics (CFD) simulation, and Fluid Structure
Interaction (FSI) simulations were carried out in an anatomically realisticmodel of a saccular cerebral aneurysm with the objective
of quantifying the effects of type of simulation on principal fluid and solid mechanics results. Eight CSD simulations, one CFD
simulation, and four FSI simulations were made.The results allowed the study of the influence of the type of material elements in
the solid, the aneurism’s wall thickness, and the type of simulation on themodeling of a human cerebral aneurysm. The simulations
use their ownwallmechanical properties of the aneurysm.Themore complex simulationwas the FSI simulation completely coupled
with hyperelasticMooney-Rivlin material, normal internal pressure, and normal variable thickness. The FSI simulation coupled in
one direction using hyperelastic Mooney-Rivlin material, normal internal pressure, and normal variable thickness is the one that
presents the most similar results with respect to the more complex FSI simulation, requiring one-fourth of the calculation time.
