Topology optimization techniques

Definition

Topology optimization techniques are computational methods used to optimize material layout within a given design space, subject to specific performance criteria and constraints. These techniques allow for the creation of lightweight, efficient structures by redistributing material where it is needed most while minimizing weight and maximizing performance. By utilizing simulations, these techniques can significantly enhance design processes in fields like engineering and manufacturing.
