Impact of blood rheology on wall shear stress in a model of the middle cerebral artery
Miguel O. Bernabeu, Rupert W. Nash, Derek Groen +4
Perturbations to the homeostatic distribution of mechanical forces exerted by blood on the endothelial layer have been correlated with vascular pathologies including intracranial a…
Flexible composition and execution of high performance, high fidelity multiscale biomedical simulations
Derek Groen, Joris Borgdorff, Carles Bona-Casas +9
Multiscale simulations are essential in the biomedical domain to accurately model human physiology. We present a modular approach for designing, constructing and executing multisca…
Choice of boundary condition for lattice-Boltzmann simulation of moderate Reynolds number flow in complex domains
Rupert W. Nash, Hywel B. Carver, Miguel O. Bernabeu +4
Modeling blood flow in larger vessels using lattice-Boltzmann methods comes with a challenging set of constraints: a complex geometry with walls and inlet/outlets at arbitrary orie…
Coalesced communication: a design pattern for complex parallel scientific software
Hywel B. Carver, Derek Groen, James Hetherington +3
We present a new design pattern for high-performance parallel scientific software, named coalesced communication. This pattern allows for a structured way to improve the communicat…
Analyzing and Modeling the Performance of the HemeLB Lattice-Boltzmann Simulation Environment
Derek Groen, James Hetherington, Hywel B. Carver +3
We investigate the performance of the HemeLB lattice-Boltzmann simulator for cerebrovascular blood flow, aimed at providing timely and clinically relevant assistance to neurosurgeo…
