Quick Intro to Permanent Magnet Modeling

June 21, 2013

I’ve written several blog entries involving permanent magnets, in one way or another. Reading those may have raised the question “what about a more simple introduction to permanent magnet simulations?” Fair enough, here’s how to model a permanent magnet and its surrounding magnetic field.

What Is COMSOL Multiphysics?

March 6, 2013

You may be wondering “What is COMSOL Multiphysics?” In short, COMSOL Multiphysics is a comprehensive simulation software environment for a wide array of applications, but structured and user-friendly for all to use. The best way to answer the question of what our software can do is to show you. This is why we have created a video that gives you a brief overview of the capabilities you can possess with the software in your hands.

Introduction to COMSOL Multiphysics, a Book to Get you Started

February 28, 2013

What does it take to get started using COMSOL Multiphysics? Of course, it depends on where you set the bar. However, grasping the workflow and handling the basic tools can be relatively easy to pick up. To make this process even smoother, first-time users will benefit from the recent major update of the COMSOL Multiphysics instruction manual. The book, Introduction to COMSOL Multiphysics, is a valuable tool for learning COMSOL simulation software and the new version is now available for […]

Multiphysics versus FEA

February 14, 2013

In a popular post from last year, I discussed accessing and manipulating the underlying equations in COMSOL. This blog post instigated reader comments, and most of the respondents appreciated, or even required, the ability to look at the mathematical model (i.e., equations) behind the physics. While considering this, I realized that there is more to the story, and with a little perspective, the community could benefit from further discussion.

Video Tutorial: Introduction to the Structural Mechanics Module

January 24, 2013

The Structural Mechanics Module has numerous capabilities, enough for a video containing all of them to last days. This video demonstrates one of the many mechanical capabilities of COMSOL Multiphysics, by outlining a Static Linear Analysis. The chosen physics interface for this problem is Solid Mechanics, one of 13 physics interfaces in the Structural Mechanics Module. The video shows step-by-step how to set up the model of a bracket with a standard workflow (i.e. import the geometry, create global parameters […]

Multiphysics Makes Single Physics Simulations Better

September 11, 2012

Coupled physics phenomena (like electrical heating, fluid structure interaction, and conjugate heat transfer) demand multiphysics, which I’ve written about previously in “What is Multiphysics?”. But what if you just have a simple analysis to do — one that has been simplified to the point where only a “single physics” (to coin a term) is considered? What benefits does multiphysics have for this?

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?
