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.111 ppapplication/pdfengCopyright is held by the author, unless otherwise indicated.
