The Giant Magneto Resistance (GMR) effect is a quantum mechanical effect which can be observed in systems consisting of thin alternating ferromagnetic and non-ferromagnetic layers. Simulation using COMSOL allows the evaluation of the magneto-resistance ratio and the electrical resistances of realistic CPP-GMR devices and opens the possibility to study new device materials and designs.

This paper describes the benefits of computational fluid dynamics in the development of a microreactor used in the desulfurization of aromatic compounds. It is crucial to verify diffusion and extinction coefficients to ensure accurate simulation results prior to experiments. COMSOL Multiphysics was used to model the behavior of all of the possible species present and reactions that may occur.

To consider effective counter measures against ground water contaminated with dense non-aqueous phase liquids (DNAPLs) such as chlorinated solvents, it is first important to understand the mechanism of their migration in heterogeneous aquifer. In addition, numerical analysis models to simulate such a complex migration in heterogeneous aquifer are required. The displacement pressure, which is ...

In an attempt to understand the mechanism and function of NAD(P)H waves in neutrophils, we have constructed a spatial model of glycolysis in neutrophils. The model does give rise to traveling NADH waves, but there are significant differences between the experimentally observed waves and the waves generated by the model. Based on the model we therefore conclude that it is doubtful that the ...

In this presentation we will show how to partially model a grand piano action. Then we will apply different touches to this virtual action and try to hear any difference. --------------------------------- Riccardo Ferrari was one of the keynote speakers at the COMSOL User's Conference, fall 2005 in Milano

Virtual prototyping is used for understanding, verifying, planning, controliing, and optimizing a technical application. It the industrial component computational science and engineering and can be called "the third pillar of modern science". The future of virtual prototyping will be multiscale and multiphysics models and simulations. --------------------------------- Keynote speaker's ...

The thin shell of the LBT Adaptive Secondary Mirror has been manufactured, optically polished, and delivered. The operations and tests required before finally mounting it on the telescope have to be run very carefully, as they imply loads completely different from the ones of the adaptive operational modes - studied in the past with very encouraging results. Deformations and stresses that occur ...

Volcanic margins are characterized by excessive magmatic activity. One of the most studied volcanic margins is the Vøring margin, offshore mid-Norway. The large volumes of magmatic rocks found there are believed to have been produced by the melting of an abnormally hot mantle. We use COMSOL Multiphysics to investigate the hypothesis that the source of this thermal anomaly was a mantle ...

The simulation of the metabolism in mammalian cells becomes a severe problem if spatial distributions must be taken into account. Especially the cytoplasma has a very complex geometric structure which cannot be handled by standard discretization techniques. In the present paper we propose a homogenization technique for computing effective diffusion constants. This is accomplished by using a ...
