  Computational fluid dynamics is intensively used to deepen the understanding
of aneurysm growth and rupture in the attempt to support physicians during
therapy planning. Numerous studies have assumed fully-rigid vessel walls in
their simulations, whose sole hemodynamics may fail to provide a satisfactory
criterion for rupture risk assessment. Moreover, direct in-vivo observations of
intracranial aneurysm pulsation have been recently reported, encouraging the
development of fluid-structure interaction for their modelling and for new
assessments. In this work, we describe a new fluid-structure interaction
benchmark setting for the careful evaluation of different aneurysm shapes. The
studied configurations consist of three real aneurysm domes positioned on a
toroidal channel. All geometric features, meshing characteristics, flow
quantities, comparisons with a rigid-wall model and corresponding plots are
provided. Reported results emphasize the alteration of flow patterns and
hemodynamic descriptors when moving from the rigid-wall model to the complete
fluid-structure interaction framework, thereby underlining the importance of
the coupling between hemodynamics and the surrounding vessel tissue.
