Define a force or moment load using magnitude and a single direction

The Magnitude and direction type lets you define a force or moment load with a magnitude and a single direction.

1. Choose Home tab→Loads and Conditions group→Force or Home tab→Loads and Conditions group→Moment .

2. In the Force or Moment dialog box, select Magnitude and direction from the Type list.

3. In the Model Objects group, click Select Object and select the geometry or FE entity to which the force or moment will be applied.

4. In the Magnitude group, define the force magnitude by entering a constant value or by using an expression or field.For more information, see Expressions. For more information, see Using fields and expressions to define boundary conditions.

5. In the Direction group, select a vector that specifies the direction of the force or moment. For more information, see Vector dialog box.

6. (Optional) In the Distribution group, select the method for distributing the force or moment over the geometry or FE entities:Select Total Per Object to apply the magnitude to each selected item and uniformly distribute the magnitude. For example, suppose you apply a 5 N force to 10 polygon edges. The software applies the 5 N force to each of the 10 polygon edges and uniformly distributes each 5 N force along the length of each polygon edge.Select Geometric Distribution to distribute the total force or moment over all the selected items based on the area. All the nodes on the selected items then get a fraction of the force or moment based on the area of the associated elements. Select Spatial to use a unitless field to map the force or moment to the nodes. For more information, see Using fields and expressions to define boundary conditions.

7. (Optional) For Abaqus analyses, in the Follower Force Option group, select the Follower check box to specify that the direction of the force should rotate with the node to which you apply it.

8. Click OK.The load is applied to the model.
