For this year's COMSOL Conference I presented how Shape and Topology Optimization can be used in a product design process. I use loudspeakers as an example the product, but the techniques can be applied across many types of products. I look at many combinations of physics and optimization, and I hav...

In a recent Dynaudio post, the headline read, “Why are all loudspeakers square boxes?” and this caught my eye, since I could not think of ANY square box loudspeakers. In fact, loudspeaker designers usually avoid this shape like the plague. In the following post, we will briefly explore the shape of...

The CAD was made so diligently that no additional repairs or modifications were needed in the sim...
