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

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

Modeling the Behavior of a Thermostat

This example exemplifies how to model applications using the *Events* Interface where a thermostat is sumlated. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Implementing a Thermostat with the Events Interface](https://www.comsol.com/blogs/implementing-a-thermostat-with-the-events-interface/) ...

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

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

Terminal Falling Velocity of a Sand Grain

The first stop for polluted water entering a water work is normally a large tank, where large particles are left to settle. Generally, gravity settling is an economical method of separating particles. If the fluid in the tank is moving at a controlled low velocity, the particles can be ... 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 ...

Helical Static Mixer

Helical static mixers are often used to mix monomers and initiators that then react during a polymerization process. The purpose of the Helical Static Mixer application is to demonstrate this mixing process as well as the use of parts and parameterized geometries when building apps. The ... En Savoir Plus

Trimmer Capacitor

A trimmer capacitor has a variable capacitance. One way of obtaining this is to use parallel facing electrodes with a variable overlap area. In this example, the capacitance can be changed by turning one electrode using a screwdriver. Typically a linear angular response is desired. ... En Savoir Plus
