If you’ve been keeping up with the blog you’ll have noticed our coverage on Toyota’s story on cooling the electronic components of their hybrid cars. This article was featured as a cover story in IEEE Spectrum’s Multiphysics Simulation insert, as well as in COMSOL News. Now we are thrilled to announce that the Principal Scientist at Toyota Research Institute of North America is going to be speaking at the COMSOL Conference in Boston this October.

Are you getting the most out of your simulations? There’s a wealth of options for creating plots and animations and for computing and exporting data in COMSOL, odds are you will find some neat features here. We want to get you off to a good start, so I’ve begun a series of tutorial videos covering a wide variety of topics in postprocessing. This tutorial series is suited for new and experienced users alike. You will get to learn the basics […]

All this talk about piezoelectricity got me thinking about how surrounded we are by everyday items whose performances rely on this physical process. Examples include inkjet printers, speakers, electric guitars, and ultrasound imaging systems. With so many different common objects utilizing this phenomenon, it may lead you to wonder: what is piezoelectricity?

Additive manufacturing, or 3D printing as it is more widely known as, is on everybody’s mind right now. Manufacturing folks, engineers, and even the general public have taken an interest in 3D printing. In other words, this is not just a fascinating phenomenon to those in the industry — additive manufacturing has been generally accepted as the next “cool” thing in manufacturing.

Much has been written lately about increasing the energy efficiency of cars. Batteries and fuel cells are very hot topics, and not so long ago I blogged about the University of Michigan’s use of solar cells to fully power a car. Yet, even on the smallest of scales, such as the sensors in your car, improvements are being made. Utilizing a MEMS (Micro Electromechanical System) piezoelectric energy harvester, Alexander Frej and Ingo Kuehne at Siemens Corporate Technology in Munich are […]

Looking for a tutorial on how to model a MEMS problem? We have recently added a video tutorial using the example of how to simulate a capacitive pressure sensor to our video gallery. For a brief overview of what you can model in the MEMS Module watch the trailer below, or go straight to the bottom of this post for a link to download the model files, which show how to produce this type of electromechanics model.

How do you simplify a 3D geometry to reduce the computational resources required to model it? Do it in 2D. What if the phenomenon can only be properly simulated in 3D? Find the planes of symmetry and reduce the size, most engineering objects are symmetric in some way. What if there is no symmetry, such as the propagation of random cracks through a steel pipe? Well, as this story from COMSOL News shows, there are other methods, such as using […]

The most common type of aortic aneurysms is that which occurs in the abdominal region. When a person experiences an abdominal aortic aneurysm (AAA), his or her abdominal aorta is dilated to the extent that its diameter is increased by over 50%. With symptoms lacking a sense of urgency (we’ve all ignored stomach pains before), if left untreated an AAA may rupture — whereon the victim’s life is on the line. An Intra-Luminal Thrombus is typically involved in AAAs, but […]

Remember those retro desk ornaments of the 1960’s, those lamps filled with colorful wax that began to move when the lamp was lit? I’m talking about lava lamps, or as I like to call them, “Rayleigh–Taylor instability machines”. They may not be popular among today’s youth, but I still own one and I thought it would be interesting to look beyond the dyed blobs of wax and observe the physics involved in lava lamps.

Amphos 21 have long been experts within environmental consulting. In particular, they have been consulting for almost twenty years within nuclear and industrial waste management, the management of water resources and contaminated land, and energy optimization. It was therefore a pleasure to see that they had started using COMSOL Multiphysics for a number of their projects, and are now officially offering consultancy services for modeling multiphysics processes within these and similar industries.
