Intracranial hemodynamics simulations: An efficient and accurate immersed boundary scheme
D. S. Lampropoulos, G. C. Bourantas, B. F. Zwick +4
Computational fluid dynamics (CFD) studies have been increasingly used for blood flow simulations in intracranial aneurysms (ICAs). However, despite the continuous progress of body…
Immersed boundary finite element method for blood flow simulation
G. C. Bourantas, D. L. Lampropoulos, B. F. Zwick +3
We present an efficient and accurate immersed boundary (IB) finite element (FE) solver for numerically solving incompressible Navier--Stokes equations. Particular emphasis is given…
Simple and robust element-free Galerkin method with interpolating shape functions for finite deformation elasticity
George Bourantas, Benjamin F. Zwick, Grand Joldes +2
In this paper, we present a meshless method belonging to the family of element-free Galerkin (EFG) methods. The distinguishing feature of the presented meshless method is that it a…
Mathematical Modeling and Computer Simulation of Needle Insertion into Soft Tissue
Adam Wittek, George Bourantas, Benjamin F. Zwick +3
In this study we present a kinematic approach to modeling needle insertion into soft tissues. The kinematic approach allows the presentation of the problem as Dirichlet-type (i.e.…
