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…
Automated modeling of brain bioelectric activity within the 3D Slicer environment
Saima Safdar, Benjamin Zwick, George Bourantas +5
Electrocorticography (ECoG) or intracranial electroencephalography (iEEG) monitors electric potential directly on the surface of the brain and can be used to inform treatment plann…
: A Reduced-Order Modeling Framework based on Machine Learning for Real-Time Applications
G. I. Drakoulas, T. V. Gortsas, G. C. Bourantas +2
Digital twins have emerged as a key technology for optimizing the performance of engineering products and systems. High-fidelity numerical simulations constitute the backbone of en…
Generation of Patient-specific Structured Hexahedral Mesh of Aortic Aneurysm Wall
Farah Alkhatib, George C. Bourantas, Adam Wittek +1
Abdominal Aortic Aneurysm (AAA) is an enlargement in the lower part of the main artery Aorta by 1.5 times its normal diameter. AAA can cause death if rupture occurs. Elective surge…
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…
