Loudspeaker Radiation: BEM Acoustics Tutorial
In this tutorial, the acoustic radiation pattern from a small generic loudspeaker is analyzed using the boundary element method (BEM). The loudspeaker is located on a small table above the floor and at a given distance from a wall. The model is set up using the Pressure Acoustics, ... Mehr lesen
Electrical Heating in a Busbar Assembly
This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Solid Edge and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep. Mehr lesen
Twisting and Bending of a Metal Frame
A thin-walled metal frame with a central cutout, modeled using the Shell interface, is subjected to twisting and bending. Around the cutout the stresses are higher than the yield stress, thus the material undergoes plastic deformation over the loading history. Mehr lesen
Glacier Flow
This example shows how to set up a glacier flow model in principle, containing several important aspects of glacier modeling: The creation of the 2D geometry, the modeling of non-Newtonian flow, and the implementation of basal sliding. In this example, two different glacier types, a cold ... Mehr lesen
Lossy Circular Waveguide
In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and ... Mehr lesen
Discharging Tank
This tutorial model illustrates how to calculate the pressure drop and initial flow rate in a pipe system connected to water tank. The Pipe Flow interface contains ready to use friction models accounting for the surface roughness of pipes as well as pressure losses in bends and valves. Mehr lesen
Tunable Evanescent Mode Cavity Filter Using a Piezo Actuator
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 ... Mehr lesen
Modeling Groundwater Contamination
A simple model for groundwater contamination portrays a well that is bored into an aquifer. The aquifer consists of a partially saturated layer and a fully saturated layer. The model investigates how much of the contaminant ends up in the well after a contaminant is introduced in the ... Mehr lesen
Stress analysis of an IGBT module under the Highly Accelerated Stress Test (HAST) condition
The Highly Accelerated Stress Test (HAST) is a testing technique to precipitate failure of electronic devices under elevated temperature and high humidity environment. This model demonstrates the structural analysis of a plastic encapsulated IGBT module under the HAST testing condition. ... Mehr lesen
Prestress of Main Bearing Cap Bolts
This example shows how to model prestressed bolts. The bolt geometry is taken from the Part Libraries. For comparison, one of the bolts is modeled using a thread contact formulation, whereas the other bolt is connected to the bolt hole by a pure continuity condition. The reduced ... Mehr lesen
