Numerical instabilities in topology optimization: A survey on procedures dealing with checkerboards, mesh-dependencies and local minima
Ole Sigmund,Joakim Petersson +1 more
TL;DR: The current knowledge about numerical instabilities such as checkerboards, mesh-dependence and local minima occurring in applications of the topology optimization method are summarized and the methods with which they can be avoided are listed.
Journal ArticleDOI
Topology optimization of fluids in Stokes flow
Thomas Borrvall,Joakim Petersson +1 more
TL;DR: In this paper, the design objective is to minimize a power function, which for the absence of body fluid forces is the dissipated power in the fluid, for the Stokes flow.
Journal ArticleDOI
Topology optimization using regularized intermediate density control
Thomas Borrvall,Joakim Petersson +1 more
TL;DR: In this paper, the authors consider topology optimization of elastic continua, where the elasticity tensor is assumed to depend linearly on the design function (density) as in the variable thickness sheet problem.
Journal ArticleDOI
Large-scale topology optimization in 3D using parallel computing
Thomas Borrvall,Joakim Petersson +1 more
TL;DR: This work considers large-scale topology optimization of elastic continua in 3D using the regularized intermediate density control introduced in [1] using the nested approach, i.e., equilibrium is solved at each iteration.
