Diffusion Processes in the Human Brain using COMSOL Multiphysics

C. Cherubini[1,2], S. Filippi[1,2], and A. Gizzi[1]
[1] Università Campus Biomedico di Roma
[2] University of Rome

This article discusses the RMN import of a brain geometry in COMSOL Multiphysics via an interpolating function. The physical property associated with the grayscale is the diffusivity tensor, assumed here to be isotropic but inhomogeneous. Applications to anti-tumor drug delivery and cancer growth processes are discussed.

Multiphysics Models of Biological Systems

S. Filippi[1,2], and C. Cherubini[1,2]
[1] Facoltà di Ingegneria Università Campus Biomedico di Roma
[2] International Center for Relativistic Astrophysics, University of Rome

This article presents different applications of COMSOL Multiphysics in the context of the mathematical modeling of biological systems. Simulations of excitable media like cardiac and neural tissues are discussed. --------------------------------- Keynote speaker's biography: Simonetta Filippi is member of the Engineering Faculty at the University Campus Biomedico and of the ...

Simulation of the Inverse Extrusion of a Brass Rod by the Coupling of Fluid, Mechanical, Thermal and Ale Modules

C. Mapelli, and L. Bergami
Politecnico di Milano

An efficient simulation of the inverse extrusion process has been performed through the coupling of three modules in COMSOL Multiphysics: fluid-dynamics, general heat transfer and ALE. The strain, the strain rate, and the stress field can be completely defined after the complete definition of the velocity field of the material under the action of the tool. The definition of the stresses and of ...

Structural Acoustic Modeling and PML's in COMSOL Multiphysics

M. Zampolli
NATO Undersea Research Centre, La spezia

In water we can’t see far, because light and electromagnetic waves are absorbed over relatively short distances. In contrast, sound travels very well in water In fact it is well known that marine mammals rely on sound for communication over large distances, and some of them even use sound to locate their target while hunting. In this presentation we provide an overview of the principles of ...
