Here are some animations and figures from my presentation at the COMSOL Conference in Cambridge last year, showing how sound fields can be manipulated using topology optimization. You can cite [1] if you want to recreate any of these.
I am happy to announce that Acculution has launched its first product. This has been in the making for a few years, and now 'A Complete Guide to - Phase Decomposition' is here (link). I have written about Phase Decomposition before (link, link), but the implementation and especially the interpretati...
In a previous post (#028) I showed how you can convert an evanescent sound field into a propagating one by using topology optimization. Now, I will briefly show that you can also use shape optimization for the same task. First, the unperturbed tube response:
Back in December 2017 COMSOL released version 5.3a of Multiphysics. I used the software on a so-called Head And Torso Simulator, HATS for short, using COMSOL's newly implemented, and highly requested, Boundary Element Method for acoustics. I had tested it in an early version (https://www.a...
