Isospectral Drums

Striking a drum excites a spectrum of vibration modes that together make up the instrument’s characteristic sound or acoustic signal. These vibration modes correspond to the eigenmodes, or eigenfunctions, of the drum’s membrane. Thus you can study this problem by solving eigenvalue ... 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

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 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

Modeling Material Removal through Thermal Ablation

This example exemplifies how to model thermal ablation by taking into account material removal. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Modeling Thermal Ablation for Material Removal](https://www.comsol.com/blogs/modeling-thermal-ablation-for-material-removal/) ...

Electrical Heating in a Busbar Assembly

This tutorial analyzes the resistive heating (Joule heating) of a busbar assembly designed to conduct a direct current from a current source to the anode in an electrolysis process. En Savoir Plus

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

Simulating Action Potential with the Hodgkin-Huxley Model

This app allows you to simulate the action potential in a cell's membrane using the Hodgkin-Huxley model. As it is presented in the form of a simulation app, you can change the input parameters for potential, conductance, and membrane capacitance to study their effects on the dynamics ... En Savoir Plus

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

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 ...
