I am working on topology optimization using the parametric level set method. Regardless of the methodology, I thought it might be a generic problem in Topology optimization with which many researchers in the field have faced. The problem is that I cannot achieve smooth boundaries even though I am using the level-set method to produce smooth boundaries. I am using two different grids and meshes for the mechanical and the level-set domains. I thought I needed to increase the number of Finite elements from 350 to 1000, but nothing changed, you can see it from the bottom right figure. Nor did increasing the number of grid cells in the level set domain improve my result.

Thank you in advance for your help.

Best regards,

Farzad
