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…
An explicit meshless point collocation solver for incompressible Navier-Stokes equations
George C. Bourantas, Benjiamin F. Zwick, Grand R. Joldes +4
We present a strong form, meshless point collocation explicit solver for the numerical solution of the transient, incompressible, viscous Navier-Stokes (N-S) equations in two dimen…
Wall Stress Distributions in Abdominal Aortic Aneurysms Do Not Correlate With Symptoms
Karol Miller, Hozan Mufty, Alastair Catlin +8
Abdominal aortic aneurysm (AAA) is a permanent and irreversible dilation of the lower region of the aorta. It is typically an asymptomatic condition that if left untreated can expa…
Biomechanical modeling and computer simulation of the brain during neurosurgery
K. Miller, G. R. Joldes, G. Bourantas +4
Computational biomechanics of the brain for neurosurgery is an emerging area of research recently gaining in importance and practical applications. This review paper presents the c…
