Research Note Abstract
Topology optimization is an emerging technology capable of producing organic shapes subject to various physical objectives. One
of the undesirable features present in the resulting triangle meshes is low-frequency surface rippling. Here we propose a method
in which the ripple frequencies are estimated based on geometric mesh characteristics. The ripples can then be removed by direct
projection to and from an orthogonal frequency basis derived from the discrete Laplace-Beltrami operator.
