Multiphysics 2007

J. Dunec
COMSOL, Palo Alto

In this presentation we present where COMSOL Multiphysics and its modules will be in the year 2007. The presentation considers the upcoming features, not only from a developers point of view, but also through examples from different branches of applied physics and mathematics. In addition, we present some important milestones during the past 10 years for COMSOL ...

Grain Boundary Migration Model in Copper Interconnects

Tim Cale, Daniel Bentz, and Max Bloomfield, RPI

We discuss the use of 3D grain continuum modeling to study grain boundary migration driven by differences in strain energy density. COMSOL Multiphysics is used to compute stresses and strain energy densities in polycrystalline structures caused by temperature changes. We treat each grain as a single crystal, with the anisotropic elastic properties of single crystal Cu appropriately rotated to ...

Analysis of Solar Hot Water Storage

K.O. Lund
Applied Chemical and Engineering Systems

In a Solar Hot Water System, the hot water from the solar collector enters at the top of the storage tank. A relevant question concerning the storage is what will the outlet temperature be. In the present work we present a way to model Solar Hot Water Systems.

Using COMSOL Multiphysics in Advanced Engineering

Advanced Computational & Engineering Services
Columbus, Ohio

In this presentation we give a thorough introduction to advanced engineering using COMSOL Multiphysics. We introduce you to many disciplines of engineering and physics as well as multidisciplinary, multiscaled multiphysics.

Using Spacers in MD Channels

A.M. Alklaibi
Technical college, Jeddah, Saudi Arabia

A membrane distillation process equipped with mesh-type material spacers has been modeled as a two-dimensional conjugate problem in which a simultaneous numerical solution of the momentum and energy of the feed and cold solutions have been carried out. The results shows that the center suspended spacer produces the highest average shear stress, and gives the highest spacer efficiency at all ...

Computer Modelling of Deformable non-Newtonian Flow using COMSOL Multiphysics

H.A. Lecuyer[1], F.H. Bertrand[1], P.A. Tanguy[1], J.P. Mmbaga[2], and R.E. Hayes[2]
[1] Ecole Polytechnique , Montreal
[2] University of Alberta, Edmonton

This presentation is concerned with the modelling of deformable non-Newtonian Flow using COMSOL Multiphysics. This general modelling approach has more concrete applications such as paper coating in a metering size press, meniscus location by PIDS to mention a few.

Deformable Medical Image Registration using the Finite Element Method

J. Li, and T.C. Zhu
Department of Radiation Oncology, University of Pennsylvania

Deformable medical image registration is studied with two models developed using COMSOL Multiphysics. One is based on the plane strain application mode and the other on the moving mesh (ALE) application mode. The models are examined by registering gross target volumes of a head-neck tumor with two sets of CT images. The comparison shows that the registration using the moving mesh (ALE) ...

Mathematical Modeling of Blood Flow in the Presence of Atherosclerosis

T. Gadkari, and A. Jeremic
McMaster University, ON, Canada

Atherosclerosis affects the arterial blood vessels causing stenosis in the arteries because of which the artery hardens resulting in loss of elasticity in the affected region. In this paper, we present an approach to model the pulsating flow of blood through such an atherosclerosis affected region of the artery using the finite element method. We further discuss the statistical model used to ...

3D Temperature Distribution during Self-Propogating High-Temperature Synthesis of Advanced Ceramics

I. Selig[1], S. Lin[1], D.L. Cocke[1], and D. Luss[2]
[1] Lamar University
[2] University of Houston

Self-propagating High-temperature Synthesis (SHS) is an economical process to produce quality advanced ceramics. In this work, SHS of solid oxide fuel (SOFC) cathode materials was modeled using COMSOL Multiphysics.

Applied Multiphysics in Thermoresistive and Magnetoresistive Sensor Models

R.W. Pryor
Pryor Knowledge Systems, Inc.
COMSOL, Certified Partner

Efficient, effective, and functional operation of autonomous systems requires a comprehensive real-time understanding, by those systems, of the embedding environment. This paper presents a brief overview of the multiphysics considerations involved in the development of models for thermoresistive and magnetoresistive sensors systems.
