Generative design for materials has recently gained significant attention due to the rapid evolution of generative deep learning models. There have been successful demonstrations of molecular-level generative design, including conditional generation based on specific criteria<sup>1</sup>. In the realm of macroscopic structures, voxel representations of two-dimensional<sup>2,3</sup> and three-dimensional<sup>4</sup> structures have been extensively studied. However, the challenge lies in the insufficient resolution of these models, hindering their ability to accurately represent real structures. Various other approaches based on point cloud<sup>5,6</sup>, mesh<sup>7</sup>, and neural radiance fields (NeRF)<sup>8–10</sup> have been explored but have yet to be introduced in the fields of material science. In this study, we aim to address these issues with a novel framework consisting of a mesh-based 3D structure generator and physics-informed functions. We utilize non-linear mapping networks as soft constraints to capture the complex nature of 3D material structures. The incorporated physics-based methods are capable of evaluating the performances of generated structures in real-time. The composition of the loss function considers these evaluation results to drive active structure optimization. Our framework endeavors to achieve high-resolution 3D structures generation guided by desired material properties, expected as a significant step forward toward the inverse design of novel functional materials. <br/><br/>References<br/>1.
