Initial Imperfection dialog box

Type
Type	Specifies how the offset distance components of the initial imperfection are defined.ComponentsUse a formula or table field to define the offset distance components as a function of spatial coordinates.Node ID TableUse a table field to define the offset distance components as a function of node ID.Note: For the dependent domain of the field, from the primary domain list, select 3-D. From the secondary domain list, select Length.
Destination Folder
Load Container	Specifies the folder in the Simulation Navigator in which the initial imperfection is stored.The list includes the root container and existing folders that you created using the New Folder command. For an initial imperfection, the root container is the Load Container.To view a hierarchical list of existing folders, click Folder Manager . To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
Appears when Type is set to Components.
Group Reference	Applies the initial imperfection to a group.For more information, see Group Reference options.
Select Object	Lets you select the geometry or FE entities on which the initial imperfection is applied.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Excluded	Lets you remove individual entities from within the selected object.
Nodes
Appears when Type is set to Node ID Table.
Select Object	Lets you select the geometry or FE entities on which the initial imperfection is applied.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Direction
CSYS	Sets the coordinate system that the software uses to apply the initial imperfection. You can select the Global coordinate system, or you can create one of the following types of local coordinate systems: Cartesian, Cylindrical, Spherical.
Components
Magnitude (Specify Field)	Lets you select or define a field that specifies the components of the offset distance as a function of node ID or spatial coordinates of the nodes.
Scale Factors	Appears when Type is set to Components.Scales the field lookup value for the corresponding offset distance component.The components that are available depend on the coordinate system type.
Plot (XY)	Appears when Type is set to Components.Plots the field as an XY graph.
Overlay(XY)	Appears when Type is set to Components.Overlays a plot on an existing plot. You can overlay up to 50 plots.
