Topology Optimization

Definition

Topology optimization is a mathematical method used to determine the best material layout within a given design space, aiming to maximize performance while minimizing weight or material usage. This approach is particularly relevant in structural engineering, as it helps to create designs that efficiently use materials by identifying where material should be concentrated or removed based on loading conditions and constraints.
