#012: BEM and Optimization in COMSOL Multiphysics 5.3a
With COMSOL introducing the Boundary Element Method (BEM) in their Acoustics interface in v5.3a, we all get some new possibilities, especially when dealing with exterior problems. Here is a little teaser of how you can combine BEM and optimization. First, I investigate a simple parameter optimization, but I as will be show later you can also do true shape optimization, if you should so desire. I have two geometries; a cylinder with height and radius of 1 m, and a small sphere

#011: Reviewing BEM in COMSOL Multiphysics
COMSOL has just announced their newest 5.3a version with the acoustic boundary element method (BEM) implemented, much to many an engineer's delight. And this is truly very good news for those of us who work in the field of acoustics. I have earlier looked at, and tested, the prerelease version, and reported my findings to COMSOL, and in the following blog post the same tests have been carried out again using the final release. I hope you will get a better understanding of the
