Co to jest Topologia Optimization?

Topology optimization is a mathematical technique that optimizes material layout with a given design domayn, under a set of loads, boundary conditions, and districtionts. The goal is to maximize a system 's performance - often minimizing compleance (maximizing stigness) for a given volume of material. Thee process involves iterative finite element analysis (FEA) where each elent' s density adiusted, grade remally remove ving material from -stress regions whing highing paths.
