COMSOL Multiphysics® Version 4

Svante Littmarck
President and CEO, COMSOL

Svante Littmarck is the CEO of the COMSOL group. He co-founded COMSOL in 1986. He holds a M.Sc. in Applied Mathematics from the Royal Institute of Technology in Stockholm. In 2004 he received an honorary doctoral degree from the Royal Institute of Technology.

Multiphase, Dual Polymer Injection Molding and Cooling of an Open Cavity to Form both Distinct and Graduated Material Properties within a Complex Three-Dimensional Body

M.S. Yeoman1
1Continuum Blue Ltd, Forest Row, United Kingdom

With the advancement of medical devices and implants, many now require more advanced nonlinear, hyper-elastic materials such as elastomers to be extensively utilized in the body. This combined with the need to allow for...

Mathematical Modeling of a Lithium Ion Battery

R. E. White1, and Long Cai2
1R.E. White & Associates LLC, Columbia, South Carolina, USA
2Department of Chemical Engineering, University of South Carolina, Columbia, South Carolina, USA

The existing lithium ion battery model in COMSOL’s Multiphysics  software is extended to include the thermal effects. The thermal behavior of a lithium ion battery is studied during the galvanostatic discharge process with and without a pulse. The existing lithium ion battery model...

Modeling of Next Generation Energy Systems by Using COMSOL: Fuel Cell, High Power Lithium Ion Battery, and Dye-Sensitized Solar Cell

Jake Kim
Samsung SDI CAE Team

In this presentation we present methods for modeling alternative energy sources such as Fuel Cells and Solar Cells. The presentation also considers aspects of the modern world and what impact the high consuming of energy sources will have on tomorrow's society. This presentation is written...

A Heat Transfer Model for Ugitech’s Continuous Casting Machine

C. Deville-Cavellin
Dr.
Liquid Metal Metallurgy and Solidification department
Ugitech’s Research Center, Ugine, France

Dr. Christian Deville-Cavellin is a Research Engineer at Ugitech's Research Center, since 1995. Ugitech, member of the Schmoltz & Bickenbach group, is a stainless steel, long products producer. C. Deville-Cavellin is responsible for all research topics related to liquid metal metallurgy and...

Modelling of Melt Cast Cooling and Solidification Processes for Explosives

P. Lamy-Bracq1 and C. Coulouarn1
1Nexter Munitions, Tarbes, France

A solidification process of casting explosives in shell is studied in this paper. An enthalpy method approach is used to model the solidification process. Both the thermal and mechanical effects are taken into account....

Large Scale Outdoor Flammable & Toxic Gas Dispersion Modelling in Industrial Environments

A. Hallgarth1, A. Zayer1, A. Gatward2, and J. Davies2

1Hazard Research & Risk Consultants Ltd, Aberystwyth, Wales, United Kingdom
2Independent Consultants, United Kingdom

HazRes has developed a gas discharge and dispersion model in COMSOL which takes into account the effects of localized wind profiles and turbulence generated by buildings, structures and terrain on the dispersion of...

FEMLAB simulation of thermoplastics injection-molding

Varela, A.E., Suárez, M.
Universidad de Carabobo, Facultad de Ingeniería, Valencia, Venezuela

The thermoplastics injection-molding process of has become one of the most important polymer processing operations in the production of molded parts with geometric complexity and high precision. Modeling and computer simulation of this process is not an easy task. Commercial computer packages...

Level Set Method for Fully Thermal-Mechanical Coupled Simulations of Filling in Injection and Micro-Injection Molding Process

M. Moguedet1, R. Le Goff1, P. Namy2, and Y. Béreaux3
1Pôle Européen de Plasturgie, Bellignat, France
2SIMTEC, Grenoble, France
3INSA de Lyon, Site de Plasturgie, Bellignat, France

In this work we tackle a more theoretical aspect of micro-injection molding, to better understand physics during the process, through numerical simulations of cavity filling. We developed a two phase flow approach by...

Multiphysics Modelling of Food Dehydration during RF Exposure

R. Renshaw1
1e2v Ltd., Essex, United Kingdom

There is a requirement for an RF (Radiofrequency) industrial dryer that will be capable of dehydrating foodstuff to the correct level after the product has been fried. RF drying should actively target moisture, due to...
