Abstract
In this chapter, an improved optimisation framework is employed for topology optimisation of PhPs and a topology refinement study is performed. The void elements of topology and relevant boundary conditions are excluded from FEM solution stage for faster fitness evaluation. Special mutation and repair operations are also implemented to smoothen the exterior boundaries of topologies and to avoid checkerboards during refinement stage.
