Design Objective - Statics dialog box

Modeling Object
Name	Sets a unique name for the design objective.
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 objective.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 the design response identifier to write to the .f06 file when you solve the solution.This label must begin with an alphabetic character.Response TypeSpecifies the response that you want to minimize or maximize.This list displays only responses that are appropriate for a statics subcase.For more information about response types, see DRESP1.Note: If you select Compliance, make sure that the Inertia Relief (INREL) check box is cleared in the Bulk Data page on the Solution dialog box for your topology optimization solution. If that check box is selected, the solve will fail.DOF1–DOF6Appears when Response Type is set to Displacement (DISP) or SPCForce (SPCFORCE).Specifies whether to apply the objective to translational (DOF1–DOF3) or rotational (DOF4–DOF6) degrees of freedom for the displacement coordinate system of the selected node.Lamina NumberAppears when Response Type is set to Composite Strain (CSTRAIN), Composite Stress (CSTRESS), or Composite Failure (CFAILURE).Sets the number of the ply layer whose response you want to minimize or maximize.Element Specification MethodAppears when Response Type is set to Strain (STRAIN), Strain Energy (ESE), Stress (STRESS), Force (FORCE), Composite Strain (CSTRAIN), Composite Stress (CSTRESS), or Composite Failure (CFAILURE).Specifies the method to use for selecting the elements to use for the response.Select Element Selection to select the elements using a group or the graphics window. Select Physical Property to select them using a physical property table.Element DimensionAppears when Response Type is set to Strain (STRAIN), Strain Energy (ESE), Stress (STRESS), or Force (FORCE), and when Element Specification Method is set to Element Selection.Specifies the dimension of the elements to use for the response, such as 3D for a tetrahedral mesh.The options that appear in this list vary, depending on your selection in the Response Type list.Element TypeAppears when Response Type is set to Strain (STRAIN), Strain Energy (ESE), Stress (STRESS), or Force (FORCE), and when Element Dimension is set to 0D or 1D.Specifies the type of element to use for the response.The options that appear in this list vary, depending on your selection in the Element Dimension list.TypeAppears when Element Specification Method is set to Physical Property.Specifies the type of physical property table to use for selecting the elements.The options that appear in this list vary, depending on your selection in the Response Type list.Physical Property Appears when Element Specification Method is set to Physical Property.Specifies the physical property table to use.If the list is extensive, click More Options to search for a particular physical property table or filter the list.You can also click Create Physical to create a new physical property table for the selected physical property type, or click Open Manager to edit an existing physical property table.Element ResultAppears when Response Type is set to Strain (STRAIN), Strain Energy (ESE), Stress (STRESS), Force (FORCE), Composite Strain (CSTRAIN), Composite Stress (CSTRESS), or Composite Failure (CFAILURE).Specifies the element result to use as the response.The options that appear in this list vary, depending on your selection in the Response Type list and other element specification options.If Item Code appears in the list, you can select that option and then set the appropriate Simcenter Nastran item code.Item CodeAppears when Element Result is set to Item Code.Sets the Simcenter Nastran item code to use as the response.Note: For some element types, the response value depends on the location setting for the structural output request. You can set this in the case control for the solution.For more information about item codes, see Item Codes.
Node Selection	Appears when Response Type is set to Displacement (DISP) or SPCForce (SPCFORCE). Group ReferenceLets you select nodes by selecting a group.For more information, see Group Reference options.Select Node Available when the Group Reference check box is cleared.Lets you select nodes in the graphics window.ExcludedLets you exclude certain nodes from selection.
Element Selection	Appears when Element Specification Method is set to Element Selection. Group ReferenceLets you select elements by selecting a group.For more information, see Group Reference options.Select 0D Element Appears when Element Dimension is set to 0D. Available when the Group Reference check box is cleared.Lets you select 0D elements in the graphics window.Select 1D Element Appears when Element Dimension is set to 1D. Available when the Group Reference check box is cleared.Lets you select 1D elements in the graphics window.Select 2D Element Appears when Element Dimension is set to 2D Shell or 2D Shear. Available when the Group Reference check box is cleared.Lets you select 2D elements in the graphics window.Select 3D Element Appears when Element Dimension is set to 3D. Available when the Group Reference check box is cleared.Lets you select 3D elements in the graphics window.ExcludedLets you exclude certain elements from selection.Note: If you select elements in the graphics window, be sure to select only elements of the appropriate type. For example, if Element Dimension is set to 1D and Element Type is set to CBEAM, you can select any 1D element, even if it is not a CBEAM element.If you select elements that are not the appropriate type, Simcenter Nastran might use unintended responses from other elements for which the response item code is still valid.
Subcase Internal Combination Method	Appears when Response Type is set to anything other than Compliance CMPLNCE).Specifies how to determine the response value to use for the subcase:AVGUses the average response value.MAXUses the maximum response value.MINUses the minimum response value.SUMUses the sum of the response values.SSQUses the sum of the squares of the response values.RSSUses the square root of the sum of the squares of the response values.For example, with a displacement response, you might select multiple nodes, and indicate that you want to use the average response for all the selected nodes.
Optimization Method	Specifies the goal of the design objective.MAXMaximizes the selected response.MINMinimizes the selected response.
Card Name	Displays the names of the Simcenter Nastran bulk entries that will be generated when you solve the solution: DESOBJ and DRESP1.
