Use the Shape Optimization Criteria dialog to set the Min Member Size for the analysis. Other Global Contraints are added automatically to the Shape Optimization Criteria dialog as they are defined.
On the Simulation Setup tab, click (Shape Optimization panel> Shape Optimization Criteria) to open the Shape Optimization Criteria dialog.
In the Shape Optimization Criteria dialog, click the green plus sign (+) next to the Global Constraints heading to add Min Member Size.
Optionally, in the Value field, input the desired minimum member size dimension.
Click OK to accept the change and close the dialog.
