I will always remember a Geotechnical Engineering class I took during the pursuit of my Civil Engineering degree. It contained both the high and low points for that academic semester; the lab portion was a lot of fun, learning about (read: playing with) the different soils and clays existing in the state of Georgia. The final project, on the other hand, tasked us with designing a retaining wall to match certain specifications — a tough and lengthy assignment. A retaining […]

When given the choice, we’d all prefer our loudspeakers to project perfect sound; having a phone conversation with someone who sounds like a robot caught in a windstorm is less than ideal. The quality of the sound is, naturally, dependent on how well the speaker is designed, and COMSOL Multiphysics is the perfect tool to simulate and optimize loudspeaker designs because of its easy-to-use multiphysics nature. For a loudspeaker analysis to be accurate, you must be able to simulate from […]

Back in January, I presented a video tutorial introducing the Structural Mechanics Module here on the blog. The video described the steps necessary to perform a static linear analysis on a bracket geometry. Now, to help you better understand the extra functionalities that exist within COMSOL Multiphysics and the Structural Mechanics Module, we are also creating additional tutorial videos of this bracket. The first two “mini-tutorials” to accompany the static linear analysis video focus on adding initial strain and thermal […]

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.

In April last year, we entered into a partnership with Siemens PLM Software and started developing the functionality that would connect COMSOL Multiphysics® simulations to Solid Edge® CAD modeling. Siemens gave us access to their tool, and we were quick in developing LiveLink™ for Solid Edge® as part of the version 4.3a release. This project led to boosting our cooperation with Simens PLM Software, as we had already implemented Parasolid® to be an integral part of the CAD Import Module […]

Induction occurs when a metal object moves in the presence of a magnetic field inducing a current in that object. The induced current causes it to heat up (called inductive heating), as all current does. Yet, simulating these two coupled physics together can be difficult to do as they are intrinsically based on different time scales. COMSOL Multiphysics is able to cleverly simulate them through combining the frequency domain modeling of the magnetic field with a stationary simulation of the […]

Students at Ohio State University can take a course on numerical simulations in biomedical engineering with Richard T. Hart. In the course, they will learn how to use computer modeling to solve biomedical engineering problems. Hart is now providing anyone who is interested in this application area with three video tutorials from the course via the Ohio State University iTunes U page.

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 […]

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 […]

On January 10th, hundreds of people tuned in to hear COMSOL and Continuum Blue discuss Structural Mechanics simulations in certain industry applications. As promised in my previous blog post on multiphysics modeling webinars happening in 2013, here is a round-up of the event — including a video excerpt detailing three structural analysis examples presented by Continuum Blue.

How do you avoid product failure down the line? By ensuring you manufacture accurate parts and assemble them correctly, of course. Manufacturing success stems from good design ideas. “Good ideas” are not conjured up at random; good ideas are those that are based on real-world physical principles. This video will show you how your company can infuse sound concepts into the early product development stages by modeling mechanical applications in COMSOL Multiphysics.
