Design Constraint dialog box

Modeling Object
Name Descriptive name for the design constraint.
Label Identifies the design constraint internally (do not modify this value).
Properties
Description A longer description for the design constraint.
Card Name Displays the name of the solver card this object will write to, DCONSTR.
Response Lets you select an existing design response to associate with this constraint.
Create Modeling Object Opens the Design Response Quantities dialog box, where you can create the response modeling object for this constraint.
Lower Bound Specifies the lower bound on the response quantity. For example, to constrain displacement of a node identified in the response, enter the lowest displacement to allow, such as –0.05 mm.Note: Make sure to enter the values in the model units. For example, if the response is for displacement, and your model units are metric, enter the value in mm.
Upper Bound Specifies the upper bound on the response quantity.
Low End of Frequency Range****High End of Frequency Range If the constraint's response is of type FRDISP, FRVELO, FRACCL, FRSPCF, FRFORC, or FRSTRE, you can specify a frequency range using the Low End of Frequency Range and High End of Frequency Range values. The Upper Bound and Lower Bound are then applicable to the response only when the value of the forcing frequency of the response falls within this frequency range.
