ComsolGrid – A Framework For Performing Large-Scale Parameter Studies Using COMSOL Multiphysics and Berkeley Open Infrastructure for Network Computing (BOINC)

C.B. Ries, and C. Schröder
University of Applied Sciences Bielefeld, Germany

BOINC (Berkeley Open Infrastructure for Network Computing) is an open-source framework for solving large-scale and complex computational problems by means of public resource computing (PRC). In contrast to massive parallel computing, PRC applications are distributed onto a large number ... Read More

Using The Time Parameter As The Third Geometrical Dimension

J. Krah
AkerSolutions, Fornebu, Norway

The paper demonstrates that for some models a 2D geometry in Cartesian coordinates can be used to obtain a 3D solution with changes in z-direction. A heat exchanger serves as an example of a practical application. The required flow rate in a straight cooling pipe penetrating ... Read More

Parameter Optimization for FEM Based Modeling of Singlet Oxygen During PDT Using COMSOL

T.C. Zhu, and X. Liang
University of Pennsylvania, Philadelphia, PA, USA

Singlet oxygen (1O2) is the major cytotoxic agent in photodynamic therapy (PDT). The reaction between 1O2 and tumor cells defines the treatment efficacy. Based on a previously developed model that incorporates the diffusion equation for the light transport in tissue and the macroscopic ... Read More
