A Recipe for Induction Stove Design Using Multiphysics Simulation
When I was little, I used to love spending the night at my grandparents’ house, where I was allowed to watch TV, stay up late, and in the morning, help my grandmother make pancakes. The hardest part was always waiting for her old, slow electric burner to heat up — to my six-year-old self, it seemed to take hours for the burner to become hot enough after we’d finished mixing the batter. Luckily for me, and for other impatient chefs […]
Mesh Refinement for Wave Problems
This week we are happy to have Kyle Koppenhoefer of AltaSim Technologies as a guest blogger. As COMSOL Certified Consultants, AltaSim can share valuable insights into using the software — today on the topic of meshing wave problems. As part of our efforts to assist COMSOL users in performing high-quality analysis, we recently used our bi-monthly email to remind users to include twelve degrees of freedom per wavelength when meshing wave problems. This article builds on our previous advice. Wave-type […]
On Solvers: Benefits and Limits of Solution Methods
This week we have the honor of having Professor Wolfgang Joppich as a guest blogger. As you may know, COMSOL Multiphysics provides great default solvers for all applications. For the interested user, it is good to know that you can optionally tune or completely change the solver settings. We strongly recommend that you read this blog posting to get an experts’ perspective on the solver technologies offered by COMSOL. I am an avid reader of the COMSOL Blog and an […]
Upgrading the Nuts and Bolts of the Electrical Grid
The electrical grid describes the network created for producing electricity, transmitting it and delivering it to the consumers. A “smart grid” is an electrical grid that gathers information on the suppliers and consumers automatically to improve efficiency and sustainability in the system. As the automated technology improves, the hardware that physically connects the electrical grid together must improve as well. This hardware, the “nuts and bolts” of the grid, is comprised of transformers, cable joints, terminations, bushings, and fault current […]
Fluid Flow: Smooth Optical Surface in Minutes
Ultra-precise optical components require blemish-free surfaces that often cannot be achieved by the machining processes that grind these components. Fluid jet polishing (FJP) is a new technology being developed by Zeeko Ltd to replace the hand polishing that was often required. With the help of COMSOL, Zeeko was able to create a product that polishes the optical components in only ten minutes instead of an entire day, and without waveforms.
Injectable Microbubbles in Hydrology and Healthcare
Microbubbles filled with oxygen can be injected into contaminated lakes to restore the water quality. Typically, water is purified via water-treatment plants, but this microbubble technique is both inexpensive and more environmentally-friendly in comparison. As seen in a COMSOL News 2011 article, oxygen microbubbles are a researcher’s way of copying nature’s own self-restoration mechanism for cleaning contaminated lakes.
The Science of Cooking, Multiphysics meets Food
It’s that time of year again for all the foodies out there; on January 29th the 2013 Bocuse d’Or will be in full swing with 24 chefs each representing their country, vying for the Gold Medal in the Olympic Games of the culinary world. In this biennial event, the chefs will have to combine classical and innovative cooking techniques to come out on top. At the last Bocuse d’Or in 2011, Gunnar Hvarnes propelled past the competition with the aid […]
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.
