Design Constraint - Buckling dialog box

Modeling Object
Name	Sets a unique name for the design constraint.
Label	Sets a unique integer for the modeling object.The dialog box automatically displays the next available modeling object number. However, you might want to change this if you use a particular series of numbers to identify certain types of modeling objects.
Properties
Description	Sets a description for the design constraint.You can also click Description to open the Description dialog box. This lets you see more of the text that you type, as well as cut, copy, or paste text.This description appears only on this dialog box.
Response Definition	Response LabelSets a unique design response identifier.This label must begin with an alphabetic character and cannot exceed eight characters.Tip: To make it easier to identify this design constraint in the optimization spreadsheet, use a descriptive label.Response TypeSpecifies the response that you want to constrain.This list displays only Buckling Modes (LAMA).Buckling Mode NumberSets the number of the buckled mode shape whose response you want to constrain.Approximation CodeSpecifies whether to use direct or inverse linearization.
Limits	LowerSets the lowest acceptable value for the buckling factor, which is a function of the direction of the load that will cause buckling. If the structure is under compression, the buckling factor is positive.UpperSets the highest acceptable value for the buckling factor.Note: If you do not want to specify a lower or upper limit, leave the corresponding box blank. If you type 0, the solver interprets that as the constraint value.
Card Name	Displays the names of the Simcenter Nastran bulk entries that will be generated when you solve the solution: DCONSTR and DRESP1.
