Topology Optimization

Topology/shape optimization is an important problem in most engineering systems for lightweight, performance enhancement, and cost reduction. EDLab is conducting researches on topology/shape optimization on structural system (e.g. civil structures, aircraft), multiphysical system (e.g. energy harvesting devices).
