[Technical Column] The Theory of OPTISHAPE-TS: "Wave Phenomenon"
The Difficulty of Nonparametric Optimization! Introduction to a Technical Column
In the previous discussion, I explained that the checkerboard phenomenon is a challenging issue in topology optimization. I also discussed a technique called filtering as a workaround, but highlighted the difficulty in finding the right balance for its application. Additionally, a completely different approach has been proposed to avoid the checkerboard pattern without modifying the optimization problem. This idea involves using design variables at the nodes rather than at the elements, and interpolating within elements using a C^0 continuous function. Please feel free to download and take a look.
