Acoustic-Structure Interaction and Air Flow in Violins

These models are featured in the blog post [Analyze Violin Tone and Volume with Multiphysics Modeling](http://www.comsol.com/blogs/analyze-violin-tone-and-volume-with-multiphysics-modeling/). One applies acoustic-structure interaction to study how the air mode resonance is affected by ... En Savoir Plus

How to Generate Randomized Inhomogeneous Material Data

These examples demonstrate how to generate and visualize randomized material data with specified statistical properties determined by a spectral density distribution by using the tools available under the _Results_ node. In the blog post associated with these files, "[How to Generate ... En Savoir Plus

Modeling Phase Change with Hysteresis

This example exemplifies how to model thermal phase change that is subject to hysteresis. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "[Thermal Modeling of Phase-Change Materials with Hysteresis](https://www.comsol.com/blogs/thermal-modeling-of-phase-change-materials-with-hysteresis/) ...

Modeling Irregular Shapes by Using Interpolation and Image Data

This file shows how to create a surface of an irregular shape based on text, image, or elevation data. This approach is best suited for data where the height (or elevation) is a function of _x_- and _y_-coordinates. The data is of the Matterhorn, a European mountain located in the ... En Savoir Plus

Beam Subjected to Traveling Load

As an example of how to build an app using the Application Builder, this application simulates the transient response of a beam, or bridge, that is placed on several equidistant supports and is subjected to a traveling load. The purpose of the Beam Subjected to Traveling Load app is to ... En Savoir Plus

Cavity Eigenfrequency Modeling Using the Electromagnetic Waves, Beam Envelopes Interface

This model demonstrates three different ways to find the eigenfrequencies of a rectangular metallic cavity. The first method uses an eigenfrequency study step together with the Electromagnetic Waves, Beam Envelopes interface. Here, it is important to define a wave vector for the physics ... En Savoir Plus

Image to Curve Add-In Examples

These example models demonstrate using the Image to Curve add-in, which is included in COMSOL Multiphysics® version 5.5. One example shows a simple structural analysis. An image of an H-beam is imported to a work plane and then extruded. A distributed load is applied to the beam ... En Savoir Plus

Modifying Imported CAD Geometry with the Deformed Geometry Interface

When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ...

Shock Tube

The compressible Euler equations are implemented in the Wave Form PDE interface with nodal discontinuous Lagrange shape functions to compute the flow in a shock tube. The purpose of this application is to simulate the flow in the tube and estimate the distributions of pressure, density, ... En Savoir Plus

Carburizing of gears

The model illustrates how to simulate carburizing, a heat treatment process producing a wear resistant surface. The model solves heat transfer in solids, carbon diffusion and phase transformation of austenite into martensite and pearlite. En Savoir Plus
