Looking for ways to cut down on the time and computer memory required to run your simulation? Does your model exhibit some form of symmetry — axial symmetry, lines or planes of symmetry, or antisymmetry for example? Or perhaps your model exhibits periodicity? If you answered yes to those questions, you’re in luck. You can model symmetry or periodicity in COMSOL Multiphysics easily by either using a 1D or 2D axisymmetric dimensional simulation or by incorporating boundary conditions that represent […]

Online engineering magazines, like Design World and Desktop Engineering, are great for anyone out there interested in emerging technologies. I especially liked a few recent articles: two in Design World’s “CAE Solutions” section and one in Desktop Engineering’s simulation section, detailing a couple of major topics important to finite element analysis, or FEA. First there is meshing, the foundation of FEA software. Second, there is optimization, which is all about maximizing efficiency and improving results. The key for any production […]

There is sometimes a need to include data from other simulation packages into a COMSOL Multiphysics model. There are a variety of ways in which this can be done, but one of the easiest approaches is to read in the point cloud data via a spreadsheet format text file. In this blog post, we walk through the steps of reading in such data, and using it in a COMSOL model.

For a transient simulation, imagine if you could simply insert a virtual sensor in a model at a certain location and then monitor the evolution of a field value over time while solving. In COMSOL Multiphysics you can do just that by using Probes. You define a probe in the Model Builder tree right under the Model Definitions node. Measuring the value at a point is not the only thing you can do with probes, but in this blog post […]

The beauty of COMSOL is that it provides a unified modeling platform no matter what type of simulations you are performing. This is almost unique to the CAE market. Recently we showed you how to model chemical reactions using a monolith reactor as our example. First we walked you through solving the reaction kinetics and then involving plug flow, next we created a full-scale 3D model of the reactor. A chemical engineer may feel comfortable using a software optimized for […]

About 13% of the world’s power is nuclear. During the 1990′s, this figure was almost 18%. This trend may continue to decline or undergo a renaissance, but in the meantime nuclear waste disposal remains a hot topic among engineers and governmental agencies. Safe procedures for the disposal of nuclear waste have been in place for decades, and continued improvement of these techniques remain in discussion today.

I love trees and my favorite is definitely the ficus, all varieties included. A few weeks ago I had the chance to admire a stately ficus microcarpa (see figure below). What struck me above all were its aerial roots. Roots are designed to absorb water and nutrients, sustaining the tree and synthesizing substances responsible for its growth. A thought crossed my mind right away: the shape of those roots and the way they coalesce have surely been optimized by Mother […]

Graphene is a special type of material consisting of a single layer of carbon atoms arranged in a hexagonal lattice. Graphene in its stable form was discovered at the University of Manchester in 2003 (coincidentally while I was there studying for my Masters degree) and resulted in Nobel Prizes in 2010 for the two researchers who discovered it. Recently, graphene has been making the mainstream news; the European Commission has pledged €1 billion (yes, that’s billion with a b) to […]

In February we asked you to mark your calendars for the COMSOL Conference 2013. Now I would like to let you know that registration is open, as well as share some important deadlines of this great event with you. The COMSOL Conference 2013 is moving across the world, making stops in the U.S., Europe, and Asia — will we see you there?

Water purification is the process by which chemicals, contaminants, and sediments are removed from dirty water to make it clean, and there are many processes through which this can be done. What you might not know, is that ozone molecules can be used as a means of disinfection in the purification process. “Ozonation” has been used to purify water, kill germs and bacteria in food, and even get rid of bad smells. Not only does ozonation provide clean water without […]
