This shows how a Gaussian beam incident on a periodic structure can be efficiently simulated. This could be applied to structured surfaces like metasurfaces or diffraction gratings. Because of superposition, only a single unit cell needs to be simulated. This can provide extremely ... En savoir plus
This example uses the Electric Currents in Layered Shells interface and the Layered Shell interface to model a piezoresistive pressure sensor. The tutorial considers the design of the MPX100 series pressure sensors originally manufactured by Motorola Inc. Although the sensor is no ... En savoir plus
Cross-coupled forces present in a hydrodynamic bearing often act as a negative damping in a rotor. Near the critical speed, this may lead to uncontrolled vibration of the turbocharger causing a risk of bearing failure. In this example, the influence of the cross-coupling forces on the ...

Kinetic analysis of catalytic reactions is essential for understanding rate behavior as well as the reaction mechanism. Developing knowledge of intrinsic reaction kinetics and of rate equations is central to reaction engineering studies aimed at improving reactor design. This model ... En savoir plus
Recovery of precious metals in recycling of electronics, or extraction from ore, is usually performed through leaching of the metal into an aqueous phase. Precious metals require the use of an oxidant, and often, a complexant. In the case of gold, the cyanide anion (CN-) forms a soluble ... En savoir plus
In nature, geckos use dry adhesion forces to climb walls. They have inspired researchers to develop synthetic gecko foot hairs to be used in, for example, robot applications. This model contains the nano/micro hierarchy of a synthetic gecko foot hair, where cantilever beams both in nano ... En savoir plus
This model evaluates the temperature distribution in 3 buried cables in a situation where the soil surface temperature is known. The temperature profile obtained with a thermal circuit approach for the cables is compared with a FEM approach. The thermal circuit properties are established ... En savoir plus
A homopolar generator is composed of an electrically conductive rotating disc placed in a uniform magnetic field that is perpendicular to the plane of rotation. The motion of the conductor through the static magnetic field induces Lorentz currents in the disc. By connecting the outside ... En savoir plus
In this example, phase transformation data and phase material properties are imported from JMatPro, and used to compute CCT curves. Dilatometry curves (axial thermal strain) are computed across a range of cooling rates. En savoir plus
This is a primer model of a permanent magnet machine. It is a generic model that can be modified to simulate a motor or generator. It demonstrates different capabilities of COMSOL Multiphysics® to examine aspects of machine design, such as air gap magnetomotive force (MMF), ... En savoir plus
