Topology optimization problems can be solved by relaxing the discrete optimization problem to a continuous optimization problem using the density method; see Theory for Topology Optimization. The
Density Model feature adds a material volume factor as a control variable in a custom selection. A minimum length scale can be imposed together with common options for projection and interpolation. It is up to you as the user to use the penalized material volume factor to interpolate material properties; see the
Topology Optimization of an MBB Beam or
Minimizing the Flow Velocity in a Microchannel models for examples of topology optimization in structural and fluid mechanics, respectively. The following is a list of topology optimization features
