Abstract

We propose a very simple heuristic to suppress gray-scale material in topology optimization in optimality criterion-like implementations. Gray-scale suppression (GSS) is recommended for use in conjunction with the SIMP material description, although gray-scale suppression in itself is adequate to effect predominantly black-and-white designs. Minimal changes are required to incorporate the gray-scale suppression technique in Sigmund’s popular 99-line Matlab code for topology optimization.
