Turbine Stator Blade Cooling and Aircraft Engines
Technology and mechanics enthusiasts might agree that engines are very cool — and they also know how fussy they get when running into cooling problems. When it comes to aircraft propulsion, overheating is not an option. Most planes can’t fly safely without an engine, so why run the risk of overheating? While current engine designs limit that risk using clever cooling systems, another path to solve this problem would be to design more energy-efficient engines, exempt from excessive heat release. […]

Using a Microfluidic Valve to Separate Charged Particles
When you think of a valve, what is the first thing that comes to mind? Electromagnetic waves, or perhaps, Stokes flow separating charged chemicals in a microchannel system? Maybe neither. The truth is, when researchers try to separate small (in the picoliters region), well-defined sample volumes of chemicals, the dispensing accuracy provided by a mechanical regulator probably won’t suffice. An electrokinetic valve, a type of microfluidic valve, on the other hand, provides the perfect solution by giving researchers the flow […]

Video: 2D Models from Cross Sections of 3D Geometries
A while back, I blogged about a new feature made available in COMSOL Multiphysics 4.3b, the ability to create 2D models from the cross sections of 3D geometries. We are so excited for this new feature that we decided to make a video showing you how easy it is to use.

Double Pendulum Simulation Tutorial
Dynamic simulation of a double pendulum system can easily be performed using the Multibody Dynamics Module available in COMSOL Multiphysics. This module enables the mechanical simulations of assemblies of flexible and rigid bodies, often coupled with other phenomena such as from heat, electrical, and others.

Digging into COMSOL’s Geomechanics Module
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 […]

Calling All Audiophiles: Loudspeaker Analysis Video
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 […]

What Is COMSOL Multiphysics?
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.

Boosting COMSOL’s Cooperation with Siemens PLM Software
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 […]

Inductive Heating of a Billet Simulation Tutorial
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 […]

Joule Heating Simulations Tutorial
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 […]

Industry: Continuum Blue Simulates Structural Mechanics
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.

Video: Modeling Mechanical Applications
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.

Keynote Video: Multiphysics Solutions for Advanced Vehicle R&D
Hybrid vehicles are no longer a new concept, but that does not mean research and development (R&D) has ceased. If anything, it is ramping up as demand for hybrid design optimization continues to grow. Ercan Dede from Toyota Research Institute of North America held a keynote talk at the COMSOL Conference Boston 2012 on how they are using multiphysics modeling for advanced vehicle systems R&D. If you weren’t there, you can now watch his keynote in a video format instead.

Keynote Video: Multiphysics Simulation for Patient Safety
The second video in our COMSOL Conference Boston 2012 keynote series features Dr. Alan Leewood’s presentation on the use of multiphysics simulation for medical safety applications. The focus of this presentation is on the safety of passive conductive implants during MRI screenings.

First Keynote Video Takes Us to Babel
One of the differences between this year’s COMSOL Conference, and previous years’, is that this year we filmed a lot of it. During the next few weeks we will be publishing some of these videos for those that were there, to enjoy it once again, and for those that weren’t to get a taste of what went on. To kick these all off, I’m proud to present the first keynote video, which takes us to Babel.

New Product Video Tutorial: LiveLink™ for Solid Edge®
With the latest COMSOL release, Version 4.3a, comes new CAD interoperability. We are delighted to introduce LiveLink™ for Solid Edge® seamless associativity between Siemens’ CAD experience and COMSOL’s multiphysics simulation software. A LiveLink™ for Solid Edge® video tutorial demonstrates this integration, and gives you a leg up in your design modeling. In this video, the three main features to help you design, optimize, and troubleshoot your geometries are demonstrated.
