Defining Nonuniform Force Loads

1. In the Simulation study tree, right-click the External Loads icon and select Force.

   The Force PropertyManager appears.

2. Click inside the Faces, Edges, Vertices, and Reference Points for Force box , then select the entity to which the force is applied.
3. Click Selected direction.
4. Click inside the Face, Edge, Plane, Axis for Direction box then select an entity to specify direction.
5. If you have selected more than one bodies to apply force, select either Per item or Total.
6. Select the desired Unit .
7. Under Force, click the desired force components and type in a value for each.
   • If you select a face or a plane for direction, specify at least one of the following components: Along Plane Dir 1 , Along Plane Dir 2 , or Normal to Plane .
   • If you select an edge for direction, specify the force value along that edge .
   • If you select an axis for direction, specify at least one of the following components: Radial , Circumferential , or Axial .
8. Check Nonuniform Distribution.
9. Click inside the Select Coordinate System box then select a coordinate system from the graphics area or from the FeatureManager tree.
10. Type the coefficients of the nonuniform distribution and click .

1. In the Simulation study tree, right-click the External Loads icon and select Force.

   The Force PropertyManager appears.

2. In the graphics area, click the faces to which you want to apply the force.
   Normal force to the selected faces is applied by default.

3. Under Unit , select a unit system.
4. In Force Value , type in the value of the normal force.
5. If you have selected more than one bodies to apply force, select either Per item or Total.
6. Check Nonuniform Distribution.
7. Click inside the Select a Coordinate System box then select a coordinate system from the graphics area or from the FeatureManager tree.
8. Type the coefficients of the nonuniform distribution and click .

If a distribution is specified such that forces change direction on part of the edge or a face as illustrated in the figure, the program sets the summation of the absolute values of the forces equal to the value specified in the PropertyManager.

When applying a nonuniform force that changes its direction [Figure(1)], split the load entity where the force changes its direction and apply the force in two steps [Figure (2) & Figure (3)].
