| Summary: | The Team for Advanced Flow Simulation and Modeling (T*AFSM) at Rice University
has been developing techniques to address the computational challenges involved
in fluid-structure interaction (FSI) modeling. The Stabilized Space-Time FSI
(SSTFSI) core technologies, in conjunction with an array of special techniques, is used
in a comparative study of patient-specific cerebral aneurysms. Ten cases, from three
different locations, are studied, half of which were ruptured. The study compares the
wall shear stress, oscillatory shear index, and the arterial-wall stress and stretch, with
the original motivation of finding significant differences between ruptured and unruptured
aneurysms. Simpler approaches to computer modeling of cerebral aneurysms
are also compared to FSI modeling.
