What Is Multiphysics?

September 4, 2012

If you’re a cynic (like I am sometimes), the term “multiphysics” might irk you. There’s only one set of physical laws, after all. There’s nothing “multi” about it. So what is multiphysics?

Video Tutorial: Create 1D Plots in COMSOL

August 28, 2012

Would you like to plot your own expressions in COMSOL? Have you ever wanted the power to measure parameters from your virtual model at whatever point you’d like, just as you would in a physical model? This new postprocessing tutorial video duo explains how to create 1D plots in COMSOL.

Video Tutorial: Creating and Customizing Plots in COMSOL

August 7, 2012

As promised, I’m back to introduce to you the second tutorial video in the new postprocessing blog series. This video covers the basics of creating plots, including some useful ways you can tweak and customize your plots. For example, have you ever wanted to improve the resolution of a plot, add or modify titles and axis labels, standardize the color bars over multiple graphs in one plot group, modify a deformation plot’s scaling, or view multiple plots in the COMSOL […]

How to Create High-Resolution Images of COMSOL Models for Articles and Papers

August 2, 2012

It has been some time since we’ve had the “Tips & Tricks” column in COMSOL News. Many people have asked me for tips on how to use COMSOL Multiphysics, so I figured I would share some with you here on the blog. The first in this new series of tips and tricks explains how you can create high-resolution images of COMSOL models.

Improving Ultrasound Imaging Systems by Directing Sound Waves

June 29, 2012

In an earlier blog post, I commented on how acoustic waves are being used in a biomedical setting, to identify malaria in small fluid samples. A more traditional use of piezoelectric devices was written about in the latest COMSOL News. Here, an Italian company, Esaote S.p.A., uses them to produce improved ultrasound imaging systems.

Including Operators and Expressions in a Multiphysics Simulation Is Easier Than You Think

December 11, 2009

As most skilled COMSOL users, I am sure you know that you are not limited to just selecting what is in our drop-down lists. Say that you have invented your own measure of structural stress. You want it to be equal to the quadratic mean of the Tresca and von Mises stresses. Go to Plot Parameters to find out what these predefined stresses are called (trescasmsld and misessmsld if you are modeling in 3D with the Structural Mechanics Module). Now […]
