Since the optimization results obtained by topology optimization depend on the size of the design domain, it is desirable to optimize the design domain as well during topology optimization. In this study, we propose a method to optimize the structura

Finite element mesh quality, which affects analysis accuracy and computational cost, is usually determined based on the designer's experience. In this study, we propose a GCN (Graph Convolutional network)-based method for evaluating the quality of 3D

In this study, we propose a novel shape optimization method for designing micro- and macro-structures concurrently. We assume the macro-structure consists of several arbitrary domains, which have different periodic micro-structures. The macro-structu
