To Create a Mass Fraction Design Constraint
1. Click
Home >
Design Constraint. The
Design Constraint dialog box opens.
2. In the Name box, type a name for the design constraint.
3. To change the color used for the design constraint, click
, and select a color in the
Color Editor dialog box.
4. To define the physical feature to use as a constraint, in the Response type box, select Mass Fraction (MASSFR).
5. To define all or a portion of the model to which the design constraint applies, next to Constraint target, do one of the following:
◦ To apply the design constraint to the entire model, select the All design regions check box.
◦ To apply the design constraint to only a portion of the model, clear the All design regions check box, and then do the following:
▪ To include items for this design constraint, click the Volumes, Components collector, and then select volumes or components.
▪ To exclude regions from the optimization for this design constraint, click the Excluded regions collector, and select volumes to exclude.
6. Under Constraint Bounds, type a value for Lower Bound and Upper Bound.
7. Select an option for Bound Type:
◦ Actual—Use the actual value as the constraint bounds.
◦ Scale of initial—Use a percentage of the initial response value as the constraint bounds.
8. Click OK.
