Finite topology as applied to image analysis
WebApr 13, 2024 · This paper proposes a density-based topology optimization method for natural convection problems using the lattice Boltzmann method (LBM). As the LBM can be developed as a completely explicit scheme, its attractive features over the traditional ones, such as the finite element method, are (1) suitability for solving unsteady flow problems … WebHere, a two-resolution scheme is developed to eliminate the above design problem. In earlier works, it is known that the two/multi-resolution scheme is generally applied to reduce the computational cost and gain high-resolution designs [57], [58], where different levels of discretization meshes are built to decouple finite element analysis, topology …
