Webb10 apr. 2024 · SIMP-based topology optimization unavoidably involves a large number of intermediate densities that makes the process planning job unnecessarily difficult. Employment of a sharp Heaviside projection may relieve this issue but the introduced high nonlinearity definitely will degrade the convergence stability [50] , especially given the … There are various implementation methodologies that have been used to solve topology optimization problems. Solving topology optimization problems in a discrete sense is done by discretizing the design domain into finite elements. The material densities inside these elements are then treated as the problem variables. In this case material density of one indicates the presence of material, while z…
