Multi-scale modeling of arterial blood flow can shed light on the interaction between events happening at micro- and meso-scales (i.e., adhesion of red blood cells to the arterial wall, clot formation) and at macro-scales (i.e., change in flow patterns due to the clot). Coupled numerical simulations of such multi-scale flow require state-of-the-art computers and algorithms, along with techniques for multi-scale visualizations. This animation presents results of studies used in the development… 



A new computational paradigm in multiscale simulations: Application to brain blood flow

The computational advances that have enabled the first multiscale simulation on 190,740 processors by coupling a high-order Navier-Stokes solver with a stochastic Molecular Dynamics solver based on Dissipative Particle Dynamics are presented.

Outflow Boundary Conditions for Arterial Networks with Multiple Outlets

A new method is developed to incorporate measurements at multiple outlets, based on a time-dependent resistance boundary condition for the pressure in conjunction with a Neumann boundary conditions for the velocity, at a computational complexity comparable to the widely used Resistance or Windkessel boundary conditions.
