文摘
The free-form curve of closed B-splines is introduced as basic design primitives to realize topology optimization with small number of design variables. Complex shape of design domain is rigorously modelled by means of level-set description and Boolean operation. Topology optimization is carried out conveniently within the framework of fixed grid. Computing accuracy is ensured effectively with the use of finite cell method.
