How to Generate Randomized Inhomogeneous Material Data

June 20, 2017

Did you know there is a way to take randomized material data with specified statistical properties determined by a spectral density distribution and use it to generate and visualize results?

How to Generate Random Surfaces in COMSOL Multiphysics®

June 2, 2017

Get a comprehensive background and step-by-step guide to generating random surfaces in COMSOL Multiphysics®, such as rough surfaces and microstructures.

The Power of the Batch Sweep

February 2, 2016

Have you ever run a large parametric sweep overnight, only to discover the next morning that the parametric solver is still not finished? You may wish you could inspect the solutions for the parameters that are already computed while waiting for the last few parameters to converge. The remedy to this problem is to use a batch sweep, which automatically saves the parametric solutions that were already computed on a file that you can open for visualization and postprocessing purposes.

COMSOL Server™ Version 5.2 Supports Faster, Focused Apps

December 15, 2015

In version 5.2 of COMSOL Server™, you can now launch apps much faster and configure the browser to run only one dedicated app. The Application Libraries, available in both COMSOL Multiphysics and COMSOL Server™, have been significantly updated with lots of examples for you to use and get inspired by when creating your own apps.

Use Editor Tools to Simplify Your App-Building Process

December 8, 2015

In the Application Builder, included with COMSOL Multiphysics version 5.2, the new Editor Tools window makes it possible to create simulation apps with a lot fewer clicks of the mouse. In this blog post, we will demonstrate how to create an app with Editor Tools using a simple simulation example, as well as show how to perform common user interface creation tasks more easily.

Dielectrophoretic Separation

January 23, 2015

How can you use an electric field to control the movement of electrically neutral particles? This may sound impossible, but in this blog entry, we will see that the phenomenon of dielectrophoresis (DEP) can do the trick. We will learn how DEP can be applied to particle separation and demonstrate a very easy-to-use biomedical simulation app that is created with the Application Builder and run with COMSOL Server™.

Detecting Dark Matter Axions with a Microwave Cavity

January 5, 2015

In 1977, the axion, a type of elementary particle, was suggested as a solution to a theoretical particle physics problem: the strong charge-parity (CP) problem. Later, it was discovered that the particle may actually be a component of dark matter. Many experiments are currently underway that have the goal of detecting axions. In this blog post, we’ll focus on the Axion Dark Matter eXperiment (ADMX), which uses a microwave cavity in an attempt to accomplish this goal.

The Tuning Fork Application

November 11, 2014

In order to make it easy to get started with the Application Builder, we included a few example applications in the Application Libraries of COMSOL Multiphysics version 5.0. This blog post will give you an overview of the Tuning Fork application and the structural vibration model that it is based on.
