DOPTPRM, MINDIM

Default = no minimum member size control

MINDIM can be smaller than the mesh size. When a value smaller than the mesh size is applied, the effect is similar to checkerboard control but with the 3-phase convergence phases process and possibly a more discrete result. Minimum member size control has a 3-phase iterative process where the final phase targets the removal of the semi-dense element layer. If manufacturing constraints are applied, minimum member size control is always activated. However, the final iterative phase will not target the removal of semi-dense elements as this may have an adverse effect on manufacturing constraint preservation.
