Abstract
We present results for topology optimization of a non-Newtonian rectifier described with a differential constitutive
model. The results are novel in the sense that a differential constitutive model has not been combined with
topology optimization previously. We find that it is necessary to apply a filter on the design variables based on a
Helmholtz-type differential equation and we try to vary the filter length throughout the optimization in order to
ensure compatibility with a convex interpolation between the inverse permeability and the design variables, which
is popular within topology optimization of fluids. We test the method on a microfluidic rectifier and find solutions
topologically different from experimentally realized designs.
