A modern high-power industrial fiber laser system can deliver up to 3kW of single-mode laser radiation on to surfaces to be cut, drilled, welded or marked. Even using highly transmissive materials, the optical component used to focus the laser beam onto target surfaces can be affected ... En savoir plus
In this example, drug-release from a biomaterial matrix to damaged cell tissue is modeled. Specifically, a nerve guide delivers a regenerating drug to damaged nerve ends. The model involves detailed drug release kinetics, with rate expressions handling drug dissociation/association ... En savoir plus
This model solves the Boltzmann equation in the two-term approximation for a background of molecular and atomic hydrogen. Electron mobility and source terms are computed by suitable integration of the electron energy distribution function over electron impact cross sections. En savoir plus
This example investigates the electrical performance of a cascaded cavity filter operating in the millimeter-wave 5G band with temperature changes. The thermal variations result in structural deformations of the structure. Thus, the resonant frequencies of the filter elements (cavities) ... En savoir plus
This model solves the Boltzmann equation in two-term approximation for a mixture of nitrogen and oxygen representing a background gas of dry air. Electron transport coefficients and source terms are computed by suitable integration of the electron energy distribution function over ... En savoir plus
This model reproduces the NiCd battery model and the results presented in De Vidts' and White's paper from 1995. Ref: P. De Vidts, R. E. White, “Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode”, J. Electrochem. Soc, Vol. 142, No. 5, May 1995. En savoir plus
The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... En savoir plus
This tutorial presents a study of positive and negative corona discharges in dry air at atmospheric pressure. The discharges are sustained within two electrodes in a coaxial configuration by a high voltage DC source applied to the inner electrode. Two different types of models are used: ... En savoir plus
This tutorial models the thermal management of a polymer electrolyte membrane (PEM) fuel cell stack. Operating the stack with a similar temperature profile for all cells is important since an uneven temperature distribution may otherwise result in nonuniform water vapor condensation and ...

This tutorial shows how to model tissue heating induced by focused ultrasound. First, the stationary acoustic field in the water and the tissue are modeled to obtain the acoustic intensity distribution in the tissue. The absorbed acoustic energy is then calculated and used as the heat ... En savoir plus
