Interfacing atomistic-based with continuum-based simulation codes is now required in many multiscale physical and biological systems. We present the computational advances that have enabled the first multiscale simulation on 190,740 processors by coupling a high-order (spectral element) Navier-Stokes solver with a stochastic (coarse-grained) Molecular Dynamics solver based on Dissipative Particle Dynamics (DPD). The key contributions are proper interface conditions for overlapped domains… 

Visualizing multiscale, multiphysics simulation data: Brain blood flow

A custom ParaView reader plug-in that processes macro-scale continuum data computed by a high-order spectral element solver; and an adaptive proper orthogonal decomposition-based technique for the visualization of nonstationary velocity fields from atomistic simulations are described.

Multiscale modeling and simulation of brain blood flow.

The effectiveness of the proposed framework is demonstrated in a realistic case involving modeling the thrombus formation process taking place on the wall of a patient-specific cerebral aneurysm, highlighting the ability of multi-scale algorithms to resolve important biophysical processes that span several spatial and temporal scales.

Multiscale Simulation of Blood Flow in Brain Arteries with an Aneurysm

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

Modeling cardiovascular hemodynamics using the lattice Boltzmann method on massively parallel supercomputers

An approach for efficiently modeling the fluid movement coupled to the cell dynamics in real-patient geometries while accounting for the additional force from the expansion and contraction of the heartbeat is proposed.

Multiscale simulations of blood-flow: from a platelet to an artery

This work focuses on the objectives, methods, computational complexity and overall methodology for simulations at the level of glycocalyx, blood cells, and up to larger arteries for multiscale modeling of blood flow including blood rheology.

Parallel Contact-Aware Algorithms for Large-Scale Direct Blood Flow Simulations

This thesis presents computationally parallel-scalable algorithms for the simulation of dense deformable vesicles in two and three dimensions both in unbounded and bounded domain and introduces explicit contact constraints into the system to ensure interference-free configuration.

Multi-physics simulations of particle tracking in arterial geometries with a scalable moving window algorithm

A multi-physics adaptive window algorithm, in which individual red blood cells are explicitly modeled in a small region of interest moving through a coupled arterial fluid domain, that scales efficiently on heterogeneous architectures and enables us to perform large, highly-resolved particle-tracking simulations that would otherwise be intractable.

Scalable simulation of realistic volume fraction red blood cell flows through vascular networks

This work presents a scalable platform for the simulation of red blood cell flows through complex capillaries by modeling the physical system as a viscous fluid with immersed deformable particles and describes a parallel boundary integral equation solver for general elliptic partial differential equations.

Progress in particle-based multiscale and hybrid methods for flow applications

This work focuses on the review of particle-based multiscale and hybrid methods that have surfaced in the field of fluid mechanics over the last 20 years. We consider five established particle

The goal is the direct simulation of blood, which is model as a mixture of a Stokesian fluid and red blood cells, and the approach has three distinct characteristics: it faithfully represents the physics of RBCs by using nonlinear solid mechanics to capture the deformations of each cell, and allows for the highly non-uniform distribution of R BCs in space.

This multiscale simulation resolves the fluid into a billion volume units, embedded in a bounding space of 300 billion voxels, coupled with the concurrent motion of 300 million red blood cells, which interact with one another and with the surrounding fluid.

Combined Simulation and Experimental Study of Large Deformation of Red Blood Cells in Microfluidic Systems

A cross-sectional area threshold is identified below which the RBC membrane properties begin to dominate its flow behavior at room temperature; at physiological temperatures this effect is less profound.

Time-dependent and outflow boundary conditions for Dissipative Particle Dynamics

Direct construction of mesoscopic models from microscopic simulations.

Two mesoscopic models of Langevin dynamics and dissipative particle dynamics are constructed by coarse graining the LJ clusters into single particles by verifying that the mean force field can reproduce the equation of state of the atomistic systems within a wide density range but the radial distribution function only within the dilute and the semidilute regime.

Flow-induced clustering and alignment of vesicles and red blood cells in microcapillaries

This model combines a particle-based mesoscale simulation technique for the fluid hydrodynamics with a triangulated-membrane model and shows that already at very low HT, the deformability of RBCs implies a flow-induced cluster formation above a threshold flow velocity.

Flow instability and wall shear stress variation in intracranial aneurysms

The authors' simulations show that the pulsatile flow in aneurysms can be subject to a hydrodynamic instability during the decelerating systolic phase resulting in a high-frequency oscillation in the range of 20–50 Hz, even when the blood flow rate in the parent vessel is as low as 150 and 250 ml min−1 for cases (iii) and (i), respectively.

Analyzing Transient Turbulence in a Stenosed Carotid Artery by Proper Orthogonal Decomposition

Time- and space-window proper orthogonal decomposition (POD) was applied to quantify the different flow regimes in the occluded artery and a simplified version of the POD analysis that utilizes 2D slices only—more appropriate in the clinical setting—was investigated.
