IH-GAN: A Conditional Generative Model for Implicit Surface-Based Inverse Design of Cellular Structures. (arXiv:2103.02588v3 [cs.CE] UPDATED)

Variable-density cellular structures can overcome connectivity and
manufacturability issues of topologically optimized structures, particularly
those represented as discrete density maps. However, the optimization of such
cellular structures is challenging due to the multiscale design problem. Past
work addressing this problem generally either only optimizes the volume
fraction of single-type unit cells but ignoring the effects of unit cell
geometry on properties, or considers the geometry-property relation but builds
this relation via heuristics. In contrast, we propose a simple yet more …
