With the development of Addictive Manufacturing (AM) technology, material with designed architecture is attracting increasing attention. Topology optimization (TO) presents a systematic approach to design optimal material and structures mathematically. Multiscale topology optimization has recently been introduced, which determines the optimal material properties and simultaneously optimizes spatially varying architected material. Homogenization-based TO is a popular approach to multiscale optimization but usually does not consider how the unit cells are connected as architected material vary within the structure. In the present work, the connectivity between material architectures is thoroughly investigated and explicitly controlled by introducing a connectivity index during optimization. This is demonstrated in the multiscale optimization framework where the macroscopic structure and multiple architected material are simultaneously optimized. Finally, this approach is adopted to study coupled multiphysics design problems, e.g., mechanical-thermal systems and acoustic/optical metamaterials, demonstrated via numerical examples.
