A voxelized immersed boundary (VIB) finite element method for accurate and efficient blood flow simulation
G. C. Bourantas, B. F. Zwick, D. S. Lampropoulos +6
We present an efficient and accurate immersed boundary (IB) finite element (FE) method for internal flow problems with complex geometries (e.g., blood flow in the vascular system).…

Random boundaries: quantifying segmentation uncertainty in solutions to boundary-value problems
S. Gerry Gralton, Farah Alkhatib, Ben Zwick +3
Engineering simulations using boundary-value partial differential equations often implicitly assume that the uncertainty in the location of the boundary has a negligible impact on…

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…
