Topology Optimization

Definition

Topology optimization is a mathematical approach used to optimize material layout within a given design space, considering performance requirements and constraints. This process is particularly significant in engineering, as it allows for the creation of lightweight and efficient structures by redistributing material in a way that enhances strength while minimizing weight. The result is often innovative geometries that can improve the overall performance of components like gas turbines.
