Topology optimization is a branch of engineering and computer-aided design that aims to find the best layout or configuration of a structure or system in order to achieve a desired set of performance criteria. This optimization process typically involves determining the optimal distribution of material within a given design space to achieve the best possible performance while minimizing weight or cost. Topology optimization techniques are commonly used in various fields such as mechanical, aerospace, and civil engineering to improve the efficiency and performance of structures, components, and systems.
