What is topology optimization and why use it?
Topology optimisation (TO) is a computer-based design method used for creating efficient designs today. Fields such as aerospace, civil engineering, bio-chemical and mechanical engineering use this method proactively to create innovative design solutions that will outperform manual designs.
What exactly is topology optimization?
Topology optimization refers to software that takes advantage of the design freedoms offered by additive manufacturing. It is a generative approach, so multiple design configurations are created for experimental testing without added design work.
Is set theory important for topology?
There are concepts from set theory that are heavily used in Topology that go beyond what you describe as "the basics". Functions, inverse images, and the like are, of course, very important. Products and disjoint unions are used in many important constructions in topology. You need to know what an arbitrary product of sets is, for example.
