Street Sign Buckles in the Wind, COMSOL User Takes Home Prize
A broken street sign turned into an online contest at the Dutch university TU Delft earlier this month. The TU Delft Webcare Team challenged their social media fans to determine what wind speed led the sign to buckle over — and the winner happens to be a COMSOL user. Here’s how Rob Eling solved the street sign challenge using COMSOL Multiphysics.
Exploring the Leidenfrost Effect
The Leidenfrost effect, also known as film boiling, occurs when a liquid comes into contact with a solid that is at a temperature well above the liquid’s boiling point. Upon contact, a layer of vapor forms between the liquid-solid interface, creating a barrier between the two. There are many examples of this phenomenon, ranging from something you may have seen in your kitchen (water “dancing” around in a pan) to things you shouldn’t try at home (dipping your hand into […]
COMSOL Conference 2013 Rotterdam Keynotes on Multiphysics Applications
The COMSOL Conference 2013 Rotterdam was well-attended and highly informative. The keynotes were the high point of the event, and they were excellent examples of multiphysics applications. The sophistication of the modeling work presented by Alwin Verschueren of Philips Research Laboratories in Eindhoven, the Netherlands, and Holger Ernst and Christian Schröder of mieletec FH Bielefeld, Germany, was truly spectacular and kept all the attendees enthralled.
Meshing Your Geometry: When to Use the Various Element Types
In a previous blog entry, we introduced meshing considerations for linear static problems. One of the key concepts there was the idea of mesh convergence — as you refine the mesh, the solution will become more accurate. In this post, we will delve deeper into how to choose an appropriate mesh to start your mesh convergence studies for linear static finite element problems.
Philosophy of the Ribbon
Over the past few years, Microsoft® has introduced updates to the user interface (UI) for its Office programs. Microsoft® Office 2013 is all about being touch-screen friendly, and Microsoft® Office 2007 brought the Ribbon interface. The Microsoft® Ribbon was designed to be easier to use than the nested drop-down menus of yore. These days, it’s what we’re used to seeing when working with their tools — and we’ve come to appreciate the ease-of-use, guidance, and clear workflow overview it provides. […]
How to Identify and Resolve Singularities in the Model when Meshing
In our previous post on Meshing Considerations for Linear Static Problems, we found that, in the limit of mesh refinement, the solution to the finite element model would converge toward the true solution. We also saw that adaptive mesh refinement could be used to generate a mesh that would have smaller elements in regions where the error was higher, rather than simply using smaller elements everywhere in the model. In this post, we will examine a couple of common pitfalls […]
Meshing Considerations for Linear Static Problems
In this blog entry, we introduce meshing considerations for linear static finite element problems. This is the first in a series of postings on meshing techniques that is meant to provide guidance on how to approach the meshing of your finite element model with confidence.
Porous Media Flow Simulations for the Mining Industry with AMPHOS 21
The mining industry pre-dates sophisticated simulation software and the computers it runs on by thousands of years. As an essential modern industry, however, the technical and analytical capabilities offered by AMPHOS 21, a COMSOL Certified Consultant, are critical for both understanding and optimizing mine operations. Recently, we sponsored a webinar together with NASA Tech Briefs on “Mining and Hydrogeology: Porous Media Flow Simulations with COMSOL”, featuring environmental consultants Jorge Molinero and Elena Abarca from AMPHOS 21. Here are some of […]
