Recovery by discretization corrected particle strength exchange (DC PSE) operators
Benjamin F. Zwick, George C. Bourantas, Farah Alkhatib +2
A new recovery technique based on discretization corrected particle strength exchange (DC PSE) operators is developed in this paper. DC PSE is a collocation method that can be used…
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.…
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…
