Where Can I Find COMSOL Multiphysics Tutorial Models?

Fanny Griesmer April 15, 2014

There are two main resources for finding COMSOL Multiphysics tutorial models: our online Model Gallery and the Model Library within the software. We also continuously push out model updates that you can download to your Model Library. Here’s your guide to what these resources are and how to use them.

Branch line couplers, a type of 90-degree or quadrature hybrid coupler, are popular because they are simple to fabricate and easy to design. They are passive devices commonly used in single-antenna transmitter systems and I/Q signal splitters/combiners. Let’s look at the basics of how this type of coupler works and some of its important design aspects.

Now famous astronomer Nicolaus Copernicus was born on February 19, 1473, in Torun, Poland. His main contribution to science was the controversial concept of a heliocentric universe. Five hundred years later, we not only accept the Sun as the center of our solar system, we even support new theories of planets orbiting two stars at once.

Rockets have been refined over the past 150 years or so. Until the 1920s, when liquid-fuel rockets were invented, rockets were powered by solid propellants and oxidizers. Both these bring forth issues in how they’re handled on the ground or in flight. Private space flight companies are now working on hybrid rocket innovations to solve this problem.

It’s easy to navigate from place to place thanks to GPS, but what about once you actually get there — what about navigating indoors? From venues of leisure to buildings in flames, there are many situations where indoor location tracking is useful. GPS technology does not work inside buildings, but there are now other methods under development that will make indoor navigation possible as well.

Before conducting certain blood sample analyses, researchers need to separate the red blood cell particles from the blood plasma. Using lab-on-a-chip (LOC) technology, red blood cell separation can be achieved via magnetophoresis (i.e., motion induced by magnetic fields). Since the magnetic permeability of the particles is different from the blood plasma, their trajectory can be controlled within the flow channel of the LOC device and then separated out from the fluid.

You’ve heard the story: a couple of scientists discovered graphene when they repeatedly pulled a strip of adhesive tape off a layer of graphite. Graphene has been all the rage due to its incredible strength, low weight, and electronic properties, but it’s not the only material of its kind. There are plenty of other 2D materials to consider for electrical applications — some of which may work together with graphene, and others that can be used in its place.

You’ve seen glimpses of our new software release at the COMSOL Conference and perhaps engaged in commentary around it in social media. Today marks the official release of COMSOL Multiphysics version 4.4, and you can now learn about the software updates in detail and download it if you are on subscription.

I recently stumbled upon a neat tool from Autodesk® called “Autodesk® Homestyler”. It’s surprising to see they have rolled out a tool that is more entertaining than utilitarian, but if a CAD company were to develop something fun for the general population, I suppose an interior design app makes sense. We took it for a test-drive. Here’s how it went.

Joule heating is a fairly standard type of simulation for COMSOL users nowadays. It involves solving for electrical voltage and temperature fields simultaneously with highly temperature-dependent material properties. Controlling Joule heating is very important when designing and manufacturing electrical systems components. The electric protection group at manufacturing company Mersen France used to base their busbar and fuse designs on trial-and-error, but these days they turn to COMSOL Multiphysics.
