Initial Stress/Strain dialog box

Type
Type	Specifies how the initial stress or strain is defined.Unbalanced - On NodesApplies the initial stress or strain to the selected nodes. Unbalanced - On Element NodesApplies the initial stress or strain to the selected elements at the nodes. Unbalanced - Node ID TableDefines a stress or strain field using a node ID table, which contains a list of node IDs and corresponding stress or strain magnitudes for each degree of freedom. Unbalanced - Element/Node ID TableDefines a stress or strain field using an element ID and node ID table. Each row of the table contains an element ID, a related node ID, and corresponding stress or strain magnitudes for each degree of freedom. Unbalanced - Surface StrainDefines a surface strain on a face or an edge.Balanced - On NodesApplies the initial strain and the offset strain field to the selected nodes. Balanced - On Element NodesApplies the initial strain and the offset strain field to the selected elements at the nodes. Balanced - Node ID TableDefines a strain field using a node ID table, which contains a list of node IDs and corresponding initial strain and offset strain magnitudes for each degree of freedom. Balanced - Element/Node ID TableDefines a stress or strain field using an element ID and node ID table. Each row of the table contains an element ID, a related node ID, and corresponding initial strain and offset strain magnitudes for each degree of freedom. In a SOL 401 Balanced Strain Generation solution, only the unbalanced types are available. In a SOL 401 Multi-Step Nonlinear solution, all types are available.
Destination Folder
Load Container	Specifies the folder in the Simulation Navigator in which the boundary condition will be stored. The list includes the root container and existing folders that you created using the New Folder command. Examples of a root container include Load Container, Constraint Container, and Simulation Object Container.
Folder Manager	Displays a hierarchical listing of existing folders. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Model Objects
The following options appear when Type is set to Unbalanced - On Nodes, Unbalanced - On Element Nodes, Unbalanced - Surface Strain, Balanced - On Nodes, or Balanced - On Element Nodes.
Group Reference	Lets you apply the load to a group.For more information, see Group Reference options.
Select Object	Lets you select the geometry or FEM entities on which the load will be applied. ExcludedLets you remove individual entities from within the selected object.
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	Appears when Type is set to any option except Unbalanced - Surface Strain.Sets the coordinate system that the software uses to apply the stresses or strains. You can select Inferred from Field to use the coordinate system that was used to define the field, or you can select the Absolute or the Material coordinate system, or you can create one of the following types of local coordinate systems: Cartesian, Cylindrical, Spherical.
Components
The following options appear when Type is set to Unbalanced - On Nodes, Unbalanced - On Element Nodes, Unbalanced - Node ID Table, or Unbalanced - Element/Node ID Table.
Tensor Type	Specifies if your field defines stress values or strain values.
Specify Field	Lets you select or define a field.
Depth Scaling Factor
Specify Field	Appears when Type is set to Unbalanced - Surface Strain.Lets you select or define a depth scaling factor field.
Magnitude
Surface Strain	Appears when Type is set to Unbalanced - Surface Strain.Sets the magnitude of the surface strain.
Initial Strain
Specify Field	Appears when Type is set to Balanced - On Nodes, Balanced - On Element Nodes, Balanced - Node ID Table, or Balanced - Element/Node ID Table.Lets you select or define an initial strain field.
Offset Strain
Specify Field	Appears when Type is set to Balanced - On Nodes or Balanced - On Element Nodes.Lets you select or define an offset strain field. You can generate an offset strain field using a SOL 401 Balanced Strain Generation solution.

Additional magnitude options

You can define the magnitude with a field. You can:Click and select from these options: Select Existing Field opens the Fields dialog box, where you can select a field. A field can define a magnitude that varies with independent variables such as frequency, temperature, or time. For more information about fields, see Fields.New Field→Formula opens the Formula Field dialog box, where you can define a formula to construct a field.For more information, see Define a boundary condition using a formula field.New Field→Table opens the Table Field dialog box, where you can define tabular data to construct a field.For more information, see Define a boundary condition using a table field and Define a material property using a table field.New Field→Link opens the Linked Field dialog box, where you can construct a linked field from an existing spatial field. For more information, see Linked Field dialog box.For more information about other options in the list, see Additional magnitude options.
