The mutual inductance between a primary and secondary single turn coil in a concentric coplanar arrangement is computed using a DC, steady-state, model and compared against the analytic solution. The induced currents in the secondary coil are computed using an AC, frequency-domain, ... 詳細を見る

This model shows how to analyze a tuning fork based piezoelectric rate gyroscope. The reverse piezoelectric effect is used to drive an in-plane tuning fork mode. This mode is coupled to an out of plane mode by the Coriolis force and the resulting out of plane motion is sensed by the ... 詳細を見る

Swirl flow is an application that involves steady rotational flow around an axis. Rather than modeling this process in 3D, COMSOL Multiphysics provides a 2D axisymmetric interface where the flow in the rotational direction is still included in the equations. This example shows the ... 詳細を見る

Pitting corrosion is localized corrosion by which local cavities, pits, are formed on a seemingly initially smooth metal surface. A pit may be initiated due to small surface defects, such as inhomogeneities in composition or shape, or from mechanical abuse. How and if the pit grows ... 詳細を見る

The topology optimized Tesla microvalve is used as inspiration for a parametrized geometry. The optimization of this geometry takes erosion and dilation of the geometry into account by optimizing over a parametric sweep. In this example the optimization is driven by the worst of the 3 ... 詳細を見る

This is a model of acoustic absorption by a porous acoustic open cell foam. In porous materials the sound propagates in a network of small interconnected pores. Because the dimensions of the pores are small, losses occur due to thermal conduction and viscous friction. Acoustic foams are ... 詳細を見る

Dialysis is a widely used chemical species separation method. One such example is hemodialysis, which acts as artificial kidneys for people with renal failure. In dialysis, only specific components are allowed to diffuse through the membrane, based on differences in molecular size and ... 詳細を見る

In this example, a settlement and heave analysis of a shallow foundation resting on an unsaturated soil stratum is conducted with the Modified Cam-Clay and Extended Barcelona Basic soil models. The effect of pore suction due to movements in the phreatic line and the resulting settlement ... 詳細を見る
