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 problems develop in a variety of analyses that include acoustics, electromagnetics, and structural vibrations. Thus, this mesh refinement issue touches many different industries.

Mufflers are often located in exhaust systems or on heat, ventilation, and air conditioning (HVAC) systems, where their key functionality is to dampen the noise that is emitted from the system. A correct description of the acoustic damping (absorption and attenuation) processes in the muffler is important when designing and modeling these systems.

Dynamic simulation of a double pendulum system can easily be performed using the Multibody Dynamics Module available in COMSOL Multiphysics. This module enables the mechanical simulations of assemblies of flexible and rigid bodies, often coupled with other phenomena such as from heat, electrical, and others.

Each year, a program committee is formed about six months prior to the conference day. This is always a sign to me that a brand new conference season has formally started. Working with the program committee has been one of the most inspiring and joyful parts of my involvement with the user’s conference, and I certainly feel the same way about the program committee for the COMSOL Conference Boston 2013.

Equation-based modeling is one of the great strengths of COMSOL Multiphysics. The ability for you to easily access the equations describing the physics you are working with, and adding or manipulating them as you see fit, dramatically opens up the realm of possibilities that you can achieve through modeling and simulation. This is exemplified by the following custom model of a beating heart.

Magnetic levitation, or maglev, involves suspending materials with magnetic fields. When gravity, acceleration, and other forces weigh down on an object, they can all be counteracted by magnetic pressure. Some uses that may appear to go completely against nature can actually be explained by fundamental science.

Vacuum technology has many important applications, from semiconductor device and MEMS fabrication, to vacuum coatings for corrosion protection, optical films, and metallization. The new Molecular Flow Module provides vacuum engineers with previously unavailable tools for modeling gas flows within vacuum systems.

Starting with the release of COMSOL Multiphysics® 4.3b you can work with multiphysics simulations right from the user interface of the Autodesk® Inventor® CAD system. Called the One Window interface, this functionality is available with LiveLink™ for Inventor®. The result of the work by our external interfaces and integrations development team, the One Window interface, is a completely new environment for simulations that are embedded in the Inventor® user interface. It contains the Model Builder, Settings, and all other views you are familiar with when modeling in the COMSOL Desktop™.

Are you an engineer under the age of 35, located somewhere in the Asia-Pacific region? If the answer is yes, you are eligible to enter the All IEEE-R10 Young Engineers’ Humanitarian Challenge 2013. The contest aims to engage young engineers to solve humanitarian problems using technology and entrepreneurial leadership. Many innovative project ideas have been submitted to this engineering contest in the past, and the winners have received funding to implement them. This year it could be your project that provides the solution to a humanitarian challenge.

If you are following this space, you have probably heard us talk about the upcoming users’ conference. Some of you might still be unsure of what this event is all about and what it can offer you, so we’ve put together a “Top 5″ list of reasons why you should attend the COMSOL Conference 2013. The conference has a wide and varied range of offerings. Unlike a lot of conferences out there, you don’t have to present a paper to attend ours (although we do still encourage it, of course). As a result, over the years, we have seen participants come to our conferences for a variety of needs.
So here they are, our Top 5 Reasons to Attend the COMSOL Conference 2013:
