The Multiphysics Community Has It All for You
The number of application examples from the COMSOL user community is soaring: We saw a record-breaking 350 papers presented at the annual user conferences. While we couldn't fit every paper into this magazine, you can access all 350 papers through the Multiphysics Community web site.
In this issue of COMSOL News, we collected presentations from the 2009 user conferences that we found most inspiring. Our favorite examples of simulation at work span the universe of engineering and science. They rang from cooling super magnets in the CERN Large Hadron Collider to how NASA extracted water from the Moon, to more practical uses of modeling such as injection molding of medical implants and creating the perfect sound from line-array loudspeakers.
We hope that you enjoy this edition of COMSOL News and that you'll find these stories as much of an inspiration in your work as we have in ours.
To experience the multiphysics community first hand, we would like to invite you to the 2010 COMSOL Conferences. You will get a first look at the COMSOL API, attend over a dozen minicouses, and connect with fellow users.
