The community of structural optimisation applies implicit boundary representations on structured meshes for identifying topologies that give rise to stiff and light components. There is a growing interest in multiphysics problems, but the structured meshes constitute an obstacle for resolving the multiple length scales that occur. We demonstrate how a combination of anisotropic mesh adaptation with the most popular optimiser and boundary representation technique can produce mesh independent results for a volume minimisation problem with stress and compliance constraints.
