: On behalf of all authors, the corresponding author states that there is no conflict of interest.
: Unless explicitly stated in the text, all results presented in this work apply the same default parameters: InlineEquation removed, InlineEquation removed, InlineEquation removed. We use a density filter of radius 1.5 relative to the element size in regular 2D or 3D grid meshes consisting of squares or cubes, respectively. The patch dimensions are InlineEquation removed, InlineEquation removed and InlineEquation removed in 3D cases and InlineEquation removed, InlineEquation removed and InlineEquation removed in 2D cases. All results are obtained in our C++ Topology Optimization prototyping framework with a dependency on the open-source Eigen library for solving linear systems of equations, although any other similar linear algebra library would be equally suitable.
