Visual Modeling and Simulation of Multiscale Phenomena

RAHUL NARAIN: Visual Modeling and Simulation of Multiscale Phenomena (Under the direction of Ming C. Lin) Many large-scale systems such as human crowds, fluids, and granular materials exhibit complicated motion at many different scales, from a characteristic global behavior to important small-scale detail. Such multiscale systems are computationally expensive for traditional simulation techniqu...

MultiScale Modeling of Physical Phenomena: Adaptive Control of Models

It is common knowledge that the accuracy with which computer simulations can depict physical events depends strongly on the choice of the mathematical model of the events. Perhaps less appreciated is the notion that the error due to modeling can be defined, estimated, and used adaptively to control modeling error, provided one accepts the existence of a base model that can serve as a datum with...

Multiscale modeling of hysteretic phenomena in magnets â•ž(invited)

Blood flow multiscale phenomena.

The cardiovascular disease is one of most frequent cause deaths in modern society. The objective of this work is analyse the effect of dynamic vascular geometry (curvature, torsion, bifurcation) and pulsatile blood nature on secondary flow, wall shear stress and platelet deposition. The problem was examined as multi-scale physical phenomena using perturbation analysis and numerical modelling. T...

Multiscale Phenomena in Bruggeman Composites

Mechanical, magnetic, and transport properties of arbitrary inhomogeneous composites are investigated by a Bruggeman-type mean-field approach. The theory yields materials parameters as functions of the volume fractions, geometries, and materials constants of the phases. Each system is described by a single response parameter g, which is equal to the percolation threshold of the composite. For m...
