On slowly moving boundaries in density based structural topology optimization

Abstract eng:
Structural topology optimization problems are commonly defined using material interpolation schemes. One of the challenges observed in the review article [3] for this density based topology optimization is the slow convergence of the solvers when an almost solidand-void design is found. In this work, we numerically investigate the reasons for slowly moving boundaries, which are often encountered in practice, and attempt to indicate how this problem can be remedied.
