A stent is a wire-mesh tube used to open a coronary artery during angioplasty, a process for the removal or compression of plaque. Their design is of significance for percutaneous transluminal angioplasty with stenting. During this procedure, a stent is deployed into the blood vessel by ... En savoir plus
Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... En savoir plus
An eigenfrequency study is used to find the resonance frequency and threshold gain for an oxide-confined, GaAs-based, vertical-cavity surface-emitting laser (VCSEL). The simulations are performed in two steps. A regular eigenfrequency analysis is first performed, to find good initial ... En savoir plus
Many complex fluids of interest exhibit a combination of viscous and elastic behavior under strain. Examples of such fluids are polymer solutions and melts, oil, toothpaste, and clay, among many others. The Oldroyd-B fluid presents one of the simplest constitutive models capable of ...

This example of a simple axisymmetric condenser microphone includes all the relevant physics and determines the microphone sensitivity as well as microphone capacitance for the specific simplified microphone geometry and material parameters. It solves a fully coupled multiphysics model ... En savoir plus
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 ... En savoir plus
In this shape optimization example, the mass of a bracket is minimized by changing the size and position of a number of geometrical objects. The requirements give limits both on the lowest natural frequency, and on the maximum stress in a static load case. This means that results from ... En savoir plus
The demand for phased array antennas increases not only for the traditional military industry but also in commercial areas such 5G mobile network platforms, Internet of Things (IoT), and satellite communication applications. This example shows how to design a phased array with a beam ... En savoir plus
This benchmark model computes the transient pressure distribution and film height in a squeeze film bearing for lubrication in a nonconformal conjunction of a solid sphere and an elastic wall separated by a lubricant film. This model solves the benchmark case of hydrodynamic interaction ... En savoir plus
This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the two hot arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The ... En savoir plus
