Moment dialog box

Type
Type	Specifies how the moment load is defined:Magnitude and Direction—Defines a moment load with a magnitude and a single direction.Normal—Defines a moment load with a magnitude and a +/– direction normal to the selected geometry or element faces. Components—Defines a moment load in terms of a global or local coordinate system. For example, if you choose a local Cartesian coordinate system, you can enter moment magnitude for each of the X, Y, and Z components.Spatial Table—Defines a moment load using a set of nodes located near the spatial locations in the magnitude field. For each node in the target set, the load magnitude defined in the field is multiplied by the scale factor.Node ID Table—Defines a moment load with a node ID table, which contains a list of node IDs and corresponding scale factors for each nodal component (X,Y,Z). For each node in the node ID table, the load magnitude at the component is multiplied by the scale factor.Edge-Face—Defines a moment load on an edge using the face for the orientation. The face defines the in-plane and out-of-plane directions.
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.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 Magnitude and Direction, Normal, Components, or Edge-Face.
Group Reference	Lets you apply the moment to a group.For more information, see Group Reference options.
Select Object	Lets you select the geometry or FE entities on which the load will be 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.
Magnitude
Appears when Type is set to Magnitude and Direction, Normal, or Node ID Table.
Moment	Sets the magnitude of the moment load.For more information, see Additional magnitude options.
Associated Face
Appears when Type is set to Edge-Face.
Select Face	Lets you select a face on which to apply an edge-face moment load. The moment load must be adjacent to the selected edge.
Direction
Method	Appears when Type is set to Magnitude and Direction and Simcenter Nastran, MSC Nastran or Samcef is the specified solver.Controls whether you are specifying a static, concentrated moment or a moment that follows the movements of selected nodes in the analysis. Note: The option you select from the Method list also affects the corresponding bulk data entry that this software creates when you export or solve your solution.Along Vector (MOMENT): Defines a static, concentrated moment. Lets you define the direction of the moment by specifying a vector.Along 2 Nodes (MOMENT1): Defines a follower moment. Lets you define the direction of the moment by specifying two nodes. These direction nodes define the vector that controls the direction of the moment.Normal to 4 Nodes (MOMENT2): Defines a follower moment. Lets you define the direction of the moment by specifying four nodes. The direction of the follower moment is parallel to the cross product of the vectors from Direction Node 1 to Direction Node 2, and from Direction Node 3 to Direction Node 4.
Specify Vector	Appears when Type is set to Magnitude and Direction.Defines the direction of the load.For more information, see Vector dialog box.To reverse the direction of the vector, click Reverse Direction .
Select Direction Node	Appears when Method is set to Along 2 Nodes (MOMENT1) or Normal to 4 Nodes (MOMENT2).Lets you select the nodes that define the motion of the follower moment.
CSYS	Appears when Type is set to Components or Node ID Table.Sets the coordinate system that the software uses to apply the load. You can select the Global Cyclic Analysis or the Global coordinate system, or you can create one of the following types of local coordinate systems: Cartesian, Cylindrical, Spherical.Note: The Global Cyclic Analysis coordinate system is available only if it is defined in the FEM.
Local	Appears when Type is set to Components or Node ID Table and CSYS is set to anything other than Global.Lets you create or select a local coordinate system.For more information, see CSYS dialog box.
Components
Appears when Type is set to Components or Edge-Face.
Magnitude	Appears when Type is set to Components.Specifies the magnitude of the moment load.
Mx, My, Mz****Mr, Mt, Mz****Mr, Mt, Mp	Appear when Magnitude is set to Expressions.Sets the moment magnitude for each component. The components available depend on the coordinate system type.
Specify Field	Appears when Magnitude is set to Field.Lets you select or define a field.
Scale Factors	Appears when Magnitude is set to Field.For each component, sets the scale factor to apply to the field.The components available depend on the coordinate system type.
Shear Moment	Appears when Type is set to Edge-Face.Defines the magnitude of a moment load tangent to the selected edge.
In Plane Moment	Appears when Type is set to Edge-Face.Defines the magnitude of a moment load that is normal to the selected edge and tangent to the selected face.
Out of Plane Moment	Appears when Type is set to Edge-Face.Defines the magnitude of a moment load that is normal to the selected face.
Follower
Appears when Samcef is the specified solver and Method is set to Along Vector (MOMENT).
Follower Moment	Lets you define a follower moment. Only valid for a structural nonlinear solution.
Follower Moment Option
Appears when Abaqus is the specified solver.
Follower	Specifies that the direction of the moment load should rotate with the node to which you apply it, defining a follower moment.
Distribution
Appears when Type is set to Magnitude and Direction, Normal, Components, or Edge-Face.
Method	Specifies how the moment load is distributed over the selected objects: Total per Object Geometric distribution Spatial Spatial - Load Conservation Spatial - Components Spatial - Components - Load ConservationDistributes the total moment based on dimensionless spatial fields.The spatial fields are always mapped to global or Cartesian coordinates, even if they are defined in cylindrical or spherical coordinates.These distribution methods require special considerations. For more information, see Special considerations for specifying magnitude and distribution in separate fields.Note: The Spatial - Components and Spatial - Components - Load Conservation options appear when Type is set to Components.
Distribution Field
Specify Field	Appears when Distribution is set to Spatial, Spatial - Load Conservation, Spatial - Components, or Spatial - Components - Load Conservation.Defines how the moment load is distributed over the nodes in the selected area.
Node Search Tolerance
Appears when Type is set to Spatial Table.
Tolerance	Sets the distance from each specified location that the software searches for the nearest node. If no nodes are within the specified tolerance of a location point, that location in the magnitude field is ignored.
Scaling ID Table
Appears when Type is set to Node ID Table.
Specify Field	Lets you use a node ID table to scale the moment magnitude for the components of specific nodes.
Card Name	Displays the name of the solver card for the load.
