A review of optimization of cast parts using topology optimization - II - Topology optimization with manufacturing constraints

This is the second part of a two-paper review of optimization of cast parts. In the first paper, we focused on the application of the original topology optimization codes. The problems with the interpretation has been shown and discussed. In this paper, we introduce TopShape to overcome this lack. It is able to take manufacturing constraints for cast parts into account. The features of TopShape and its results will be discussed and compared with the result of the commercial code OptiStruct. Furthermore, a new design alternative for cast parts will be derived.
