Smart materials are able to convert one form of energy to another. These materials can be either solid or fluid, and are typically located within what’s called a smart structure. What makes these materials and structures so “smart”? Let’s find out.

In a previous blog entry I discussed some of the exotic properties of graphene. The fact that graphene consists of a single layer of atoms means the aspect ratio of any graphene-based structure may be very high. High aspect geometries present their own array of modeling challenges.

Dr. Raj Thiagarajan is a prolific producer of interesting research articles ranging from waste-water treatment to acoustics metamaterials, and lots in between. As the Managing Director at ATOA (“Atom TO Application”) Scientific Technologies, a COMSOL Certified Consultant, Raj has had to simulate all types of applications. Now he will show you how to use multiphysics simulations in multimaterial and composite product design.

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.

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 download from our website. This significant rewrite is intended to get you off to the best possible start when you’re first learning to use the software.

Heat Transfer | Posted on February 21st, 2013 by Phil Kinnane
Having used COMSOL Multiphysics for over six years now, we are pleased to have Dr. Jon Ebert, Director at SC Solutions, join us in the next Mechanical Engineering Magazine Webinar Series titled “Heat Transfer in Solid and Fluids”. On March 7th, he will co-host an instructional webinar together with COMSOL’s John Dunec. Dr. Ebert will discuss SC Solution’s simulation activities within a wide span of heat transfer-related applications, particularly with respect to semiconductor manufacturing. As a long-time user of COMSOL Multiphysics, this promises to be an interesting relation of his experiences using COMSOL for heat transfer applications.

If you’re in the business of designing transducers, resonators, actuators, or sensors, odds are you deal with piezoelectric materials — a key component in these devices. As we’ve said before, multiphysics simulation should play a central role in the product design-stages to ensure top quality without wasting time or money. For those of you who design piezoelectric devices, we have an upcoming piezoelectric simulations webinar on February 28th.

One of the classic multiphysics couplings in engineering and science is joule heating, also called resistive heating or ohmic heating. Some joule heating examples include heating of conductors in electronics, fuses, electric heaters, and power lines. When a structure is heated by electric currents, the device can reach high temperatures and either structurally degenerate or even melt. The design challenge is to remove this heat as effectively as possible. COMSOL eases these challenges by providing a specialized multiphysics interface for joule heating, allowing for quick and easy definition of the phenomenon and even includes the ability to model convection for removing the heat.
Here, we’ve produced a video resource for you to see how you can effectively simulate joule heating using COMSOL Multiphysics. The 2-chapter video tutorial demonstrates how to model the joule heating of a fuse, seeking to answer the question: “Will it blow?”.

The overarching reason why you should attend one of our multiphysics workshops is of course that you get to see COMSOL Multiphysics in action. Thinking that sounded great, albeit a bit lofty, I asked my colleague Lauren Sansone who oversees our corporate events, to spell it out more concretely. Her three reasons why you should attend are as follows:

Hydraulic fracturing (popularly referred to as “fracking”) is a method to increase production of oil and gas from certain types of geological formations. It has been used for decades, but recently, as the practice has increased, fracking has become a controversial topic. I will avoid taking sides in this debate, but the fact that there is a conflict implies there needs to be a deeper understanding of the process and its effects.
