1. Introduction
Topology optimization has been actively investigated in the past few decades, which is now a major structural design methodology. Compared to trial and errors, topology optimization employs the automatic sensitivity-driven design loops which ensures outstanding efficiency and optimality; in addition, the method does not require much about the initial guess to produce creative design solutions, which makes it widely accepted by the design community. Currently, SIMP (Solid Isotropic Material with Penalization) [1], ESO (Evolutionary Structural Optimization) [2], and level set [3,4] are the main topology optimization methods. These methods all have their unique characteristics and at the same time, are tightly associated. A broad range of design problems governed by different physical disciplines have been solved through these methods, i.e. solid mechanics [1–6], fluid dynamics [7,8], and thermal dynamics [9–11], etc. A few comprehensive literature surveys can be found in [12–14]. On the other hand, topology optimization is still poorly developed given certain engineering backgrounds. A critical challenge is the manufacturability. In the past two decades, quite a few research publications have been dedicated to addressing this challenge. Length scale control is concerned for machining parts, which has been addressed based on both SIMP [15–24] and level set [25–30]; No interior void and undercut restrictions are necessary for injection molding/casting parts, which have also been addressed based on SIMP [31–36] and level set [37–39]; recently, manufacturability of 3D printed parts has also attracted plenty of concerns [40–43].
