Mechanical Modeling of Braided Neurovascular Flow Diverters using a Beam-to-Beam and Beam-to-Surface Contact Formulation
Martin Frank, Ivo Steinbrecher, Matthias Mayr +1
Braided neurovascular flow diverters are widely used for the endovascular treatment of intracranial aneurysms, where their mechanical response and final deployed configuration are…
Contact-resolved deployment of the Contour Neurovascular System in patient-specific intracranial aneurysms
Ratnadeep Pramanik, Fina Gießler, Martin Frank +5
While intrasaccular flow disruptors are increasingly used to treat wide-necked intracranial aneurysms (IAs), many patient-specific computational workflows prescribe a pre-seated de…
Modified augmented Lagrangian preconditioning for mixed-dimensional beam-solid coupling
Max Firmbach, Ivo Steinbrecher, Alexander Popp +1
This paper presents modified augmented Lagrangian block preconditioners for the mixed-dimensional coupling of three-dimensional solid bodies with embedded one-dimensional torsion-f…
A variationally consistent beam-to-beam point coupling formulation for geometrically exact beam theories
Ivo Steinbrecher, Nora Hagmeyer, Christoph Meier +1
Slender beam-like structures frequently occur in engineering applications and often interact at discrete locations through joints or connectors. Accurate modeling of such interacti…
An Embedded Mesh Approach for Isogeometric Boundary Layers in Contact Mechanics
Eugenia Gabriela Loera Villeda, Ivo Steinbrecher, Alexander Popp
This paper proposes a novel discretization workflow for contact problems in which the discretization of the contact interface is decoupled from that of the bulk domain. This separa…
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…
Numerical simulation of endovascular treatment options for cerebral aneurysms
Martin Frank, Fabian Holzberger, Medeea Horvat +7
Predicting the long-term success of endovascular interventions in the clinical management of cerebral aneurysms requires detailed insight into the patient-specific physiological co…
An approximate block factorization preconditioner for mixed-dimensional beam-solid interaction
Max Firmbach, Ivo Steinbrecher, Alexander Popp +1
This paper presents a scalable physics-based block preconditioner for mixed-dimensional models in beam-solid interaction and their application in engineering. In particular, it stu…
A consistent mixed-dimensional coupling approach for 1D Cosserat beams and 2D surfaces in 3D space
Ivo Steinbrecher, Nora Hagmeyer, Christoph Meier +1
The present article proposes a novel computational method for coupling arbitrarily curved 1D fibers with a 2D surface as defined, e.g., by the 2D surfaces of a 3D solid body or by…
