In this tutorial, the vibrational behavior of a small aluminum plate with four waveguide structures is analyzed. This is an example of a structural component located in a device where elastic waves are propagating, like a smart speaker, an electric motor, or a MEMS device. The plate can ... En savoir plus
This model is a benchmark for three-phase flow commonly used in food processing, pharmaceutical industry, and chemical processing. The results are validated against data reported in the literature. A gas bubble rises through two layers of liquid, a lighter liquid resting on top of a ... En savoir plus
In this example, a torque is applied to the inner edge of a circular annulus-shaped membrane while the outer edge is fixed, resulting in membrane wrinkling. The wrinkling membrane model avoids the equilibrium instability that would be produced by the compressive stresses. The effect of ... En savoir plus
Thermal management of a battery pack is simulated considering two scenarios, air (natural convection) and phase change material (PCM) in the gap between the batteries. The PCM considered is a composite material of paraffin wax and graphite additive. Graphite is typically added for ... En savoir plus
An evanescent mode cavity filter can be realized by adding a structure inside of the cavity. This structure changes the resonant frequency lower than the dominant mode of the unfilled cavity. A piezo actuator is used to control the size of a small air gap which provides the tunability of ... En savoir plus
This tutorial model solves for an inductively coupled plasma reactor in a mixture of argon/oxygen. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. En savoir plus
A demonstration of topology optimization using the Structural Mechanics Module and the Optimization Module. The classical MBB beam is solved in 2D using a Helmholtz filter and Solid Isotropic Material Penalization (SIMP) technique to recast the original combinatorial optimization problem ... En savoir plus
Modeling the electrical activity in cardiac tissue is an important step in understanding the patterns of contractions and dilations in the heart. The heart produces rhythmic electrical pulses, which trigger the mechanical contractions of the muscle. A number of heart conditions involve ... En savoir plus
In this study, the compressible turbulent flow through a supersonic ejector is modeled using the High Mach Number Flow interface in the CFD Module. Ejectors are simple mechanical components used for a wide range of applications, including industrial refrigeration, vacuum generation, gas ... En savoir plus
A magnet moving axially through the center of a coil will induce a voltage across the coil terminals. One practical application of this is in shaker flashlights, where the flashlight is vigorously shaken back and forth, causing a magnet to move through a multi-turn coil, which provides ...
