Comments
 If minimum member size is activated, the threephase approach is designed to produce discrete results. However, when manufacturing constraints (including symmetry and pattern grouping) are applied, results typically can contain a semidense layer of elements. This new discrete formulation aims at producing more discrete results for all topology optimization runs including manufacturing constraints. The improved solution discreteness also helps improve the results for maximum member size control.
