Driving to work today I was filled with inspiration due to a radio report of the inspiring moment of the landing of the Curiosity on Mars. The reporter had concentrated on the leader of the rover’s entry, descent and landing engineering team, Adam Steltzner, and the star of the moment. The quote that hit me while I waited at the traffic light was “The thing that engineering and physics gave me was, there’s a right answer.” The guy had said […]

I have previously blogged about 3D printing and how it would be great if you could go from model to product in one step. Now it seems as though the Stereolithography (STL) file format is reaching its limits for being useful as a standard for this type of application. The printers themselves, and what they are capable of, are outstripping the abilities of the file formats to support their new capabilities. Moves are being made to develop a better file […]

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 […]

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 […]

Düsensauginfiltration (DSI) is a novel technique for lowering water levels at mining and construction sites while not actually having to transport the water away from these sites. This came to my attention at the latest COMSOL Conference in Stuttgart. There, Ph.D. student Yulan Jin and Assistant Professor Dr. Ekkehard Holzbecher from the Georg-August University in Göttingen, Germany was presenting their research into this groundwater lowering technique.

Did you hear that the University of Michigan’s team won the American Solar Challenge a couple of weeks ago? Back in January of this year, I blogged about how the University of Michigan team refined their solar car design and now it’s great to see them come in first in the Solar Challenge. They finished the eight-day trip ten hours ahead of the runner-up, Iowa State. This win resonates with us at COMSOL as well actually, because they used COMSOL […]

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.

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.

David Kan has previously blogged very well about the Pipe Flow Module, where he described the fundamentals behind this new product of ours. Now, you can see this module in action at a webinar run on July 19th. Check out the details and registration for the upcoming Pipe Flow Simulation Using COMSOL webinar.

During the last few months, we have been offering “lunch time tutorials” for users and others interested in multiphysics modeling. In these webinar-run tutorials, we choose an application and spend a bit of time looking at it, and how to model it in detail. We’ve already reported about an example that models a gate valve and now we are ready to offer an example related to pollution, namely that of a particle plume that spreads throughout a room.
