For certain classes of scientific and technical computations the cloud may offer easily accessible, scalable, and affordable gigantic computing power. A power that for these classes may lead to a step change in model and analysis complexity compared to what is feasible with dedicated clusters and similar networked solutions. Acoustics with or without interaction with coupled physics fields ...

The transfer of sucrose and fructooligosaccharides to melon and water to solution was modeled based on generalized form of Fick’s second law for simultaneous diffusion and resolved by the finite element method using the software package COMSOL Multiphysics® software. The diffusion coefficients, the mass transfer coefficient and the Biot number were determined using the simplex ...

The common basis of physical laws is the continuity of the action field. It implies Structural mechanics, Hydrodynamics, Quantum mechanics, Electrodynamics and the self-organisation of matter. A general tool to investigate all the basic equations is FEMLAB. In academic training it allows to take the concentration away from the manifold of mathematical methods of solutions and draw it to the real ...

Ensuring the quality of underground water and controlling its quantity is of major concern for the population. Therefore, this subject attracts many students from different specialties at different levels of their curriculum. In fact, the pedagogic objectives of the course may be different according to the level or/and interest of the students and COMSOL is used due to its versatility. In this ...

Objective of this contribution is to present a procedure for evaluating second order drift forces on floating bodies, often the most important loading component for mooring design, in case of high waves propagating in relatively shallow water depths. The non linearity associated to this condition, which is typical of installations involving wave energy converters, makes this problem particularly ...

The inverse diffusion problems deal with the estimation of many crucial parameters such as the diffusion coefficient, source properties, and boundary conditions. Such algorithms are widely applied in many design problems in different physical, chemical, and biological fields. Recently, the estimation of the boundary properties, of the diffusion process, have attracted researchers. We first ...

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.

The magnetic field gradient produced by an electromagnet gripper head depends on its design. Stochastic Methods offer certain robustness to the design optimization process. In this paper, Improved Discrete Particle Swarm Optimization (IDPSO) searching technique is applied to the shape and magnetic field gradient optimization of an electromagnet head. The magnetic field and forces are computed ...

The modeling of light propagation through multiple layers of biological tissue are assessed & compared to the theoretical predictions by Perelman at al. [94 & 95] of the most-favorable-path (MFP). The MFP on which photons will be found can be obtained from the path of the net flux propagation using the diffusion equation. The diffusion equation is valid when studying diffuse light propagation, ...
