We’ve been running these “Lunch Time Web Tutorials” over the past couple of months, featuring 45 minutes of solving a particular problem following a comprehensive step-by-step format. Each webisode involves a different type of engineering problem, one of which focused on the modeling of a gate valve in a pipe branch. We are now making this available as a set of two videos for those who missed the live tutorial.

We developed COMSOL Multiphysics to empower the engineering and science communities with state-of-the-art simulation tools. A key ingredient of this empowerment is flexibility. COMSOL users are already well aware of the full compatibility between various physics. This means you can put any (yes, really any) combination of COMSOL physics together. But that’s not the only way our multiphysics simulation tool is flexible.

According to a study done by Brunel University in the United Kingdom, the food sector is among the top five energy-consuming industries. The transportation of food, including keeping it refrigerated, is one of the larger contributing factors to this energy-consumption and subsequent greenhouse gas emissions.

Before you drink your next pint of Guinness, have a close look at the bubbles in the brew, and see if they sink. Apparently they do. Now a group of scientists from the University of Limerick in Ireland (where else?) has modeled the phenomenon of sinking bubbles in Guinness beer to lend weight to this finding and provide a theoretical explanation.

One of the interesting stories from this year’s COMSOL News is the article concerning Johnson Screens®. They manufacture steel screens to block debris in water for pipes and valves. Their challenge is to design water intake screens with openings large enough for an unimpeded flow of water, but small enough to block enough debris depending on a specific application. This means that each screen must be custom-designed taking into account the characteristics of the debris and the depth at which […]

You may already be familiar with large regenerative heat exchanger (RHX) systems, but what about much smaller micro-channel systems? That’s just the type of invention the research teams at Intellectual Ventures (IV) are working on.

The COMSOL News production continues and we’re almost done with sending all the User Stories to layout. We’ve also started to get some coming back, and they’re beginning to look great. One of them uses the new Particle Tracing Module that I blogged about recently, giving you a glimpse of what’s coming for the next release of COMSOL Multiphysics.

One of the things I have noticed from the FEM vs FVM debate is that when you want to couple other physics to fluid flow, then FEM is the best method to do this with. It’s fitting then that my colleague in our Palo Alto office, John Dunec, ran a webinar this week on Multiphysics Flow Simulations with COMSOL.
