Contact-resolved deployment of the Contour Neurovascular System in patient-specific intracranial aneurysms
Ratnadeep Pramanik, Fina Gießler, Martin Frank +4
While intrasaccular flow disruptors are widely used to treat wide-neck intracranial aneurysms, state-of-the-art patient-specific computational models routinely neglect the deployme…

Smoothed aggregation algebraic multigrid for problems with heterogeneous and anisotropic materials
Max Firmbach, Malachi Phillips, Christian Glusa +3
This paper introduces a material-aware strength-of-connection measure for smoothed aggregation algebraic multigrid methods, aimed at improving robustness for scalar partial differe…
