#013: Shape Optimization vs Analytical Solution
Before setting up any numerical calculation, you should always consider if you can get similar insight with simpler means, such as analytical expressions, lumped circuits, or similar techniques. In today's blog I look at how the result of a shape optimization simulation could actually have been investigated much easier with an analytical expression. I have several interests within the field of vibroacoustics, which hopefully shows in the different blog posts on my page. But s
#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
