Apply loads to a generative model

Learn how to apply different types of loads to the selected geometry.

To apply a force load

1. On the Define tab, click Design Conditions > Structural Loads .

   The Structural Loads dialog opens.

2. Ensure that the Force load is selected.

3. Select faces, edges, or vertices to place the load.

   You can select more than one object, but all entities must be of the same type.

   Important: You can apply loads to preserve geometries only.

4. Choose the method of specifying the load direction.

   You can select one of the following methods:

   • Normal . The load direction is normal to the object where the load is applied.
   • Angle (delta) . Specify a relative X Angle, Y Angle, and Z Angle to orient the load direction. The Angle direction is relative to the first entity selected for the load target. If you want to choose a different entity, click Select in the Reference field and choose a reference entity.
   • Vectors (x,y,z) . Specify the global force components:
     • Fx = X component
     • Fy = Y component
     • Fz = Z component

5. (Optional) Click Flip Direction to reverse the load direction.

6. Specify the magnitude of the load.

   Note: When you select several targets the Force Per Entity option appears. The option is activated and grayed out. It indicates that by default program applies the load of the specified magnitude to each of the selected targets. For example, if you select three faces and enter the magnitude of 0.5 N, you're applying the load of 0.5 N to each face. The total applied force is 1.5 N (0.5 N * 3 faces).

7. (Optional) Click Change Units to choose alternative units for inputting parameters.

8. Click OK.

   The force load is added to the active load case in the browser: Generative Model > Study - Generative > Load Case > Loads.

   Tip: To modify the applied load, do one of the following:
   • Mouse over it in the browser, and then click .
   • On the canvas, double-click the load glyph.

To apply a pressure load

1. On the Define tab, click Design Conditions > Structural Loads .

   The Structural Loads dialog opens.

2. Select the Pressure load from the drop-down list.

3. Select faces to place the load.

   You can select one or more faces.

   Important: You can apply loads to preserve geometries only.

4. (Optional) Click Flip Direction to reverse the load direction.

5. Specify the magnitude of the load.

6. (Optional) Click Change Units to choose alternative units for inputting parameters.

7. Click OK.

   The pressure load is added to the active load case in the browser: Generative Model > Study - Generative > Load Case > Loads.

   Tip: To modify the applied load, do one of the following:
   • Mouse over it in the browser, and then click .

To apply a moment load

1. On the Define tab, click Design Conditions > Structural Loads .

   The Structural Loads dialog opens.

2. Select the Moment load from the drop-down list.

3. Select face or faces to place the load.

   You can select one or more faces.

   Important: You can apply loads to preserve geometries only.

4. Choose the method of specifying the load direction.

   You can select one of the following methods:

   • Normal . The load direction is normal to the face where the load is applied.
   • Angle (delta) . Specify a relative X Angle, Y Angle, and Z Angle to orient the load direction. The Angle direction is relative to the first face selected for the load target. If you want to choose a different face, click Select in the Reference field and choose a reference face.
   • Vectors (x,y,z) . Specify the global moment components:
     • Mx = X component
     • My = Y component
     • Mz = Z component

5. (Optional) Click Flip Direction to reverse the load direction.

6. Specify the magnitude of the load.

   Note: When you select several faces the Moment Per Entity option appears. The option is activated and grayed out. It indicates that by default the program applies the load of the specified magnitude to each of the selected faces. For example, if you select four faces and enter the magnitude of 400 lb-ft, you're applying the load of 400 lb-ft to each face. The total applied moment is 1600 lb-ft (400 lb-ft * 4 faces).

7. (Optional) Click Change Units to choose alternative units for inputting parameters.

8. Click OK.

   The moment load is added to the active load case in the browser: Generative Model > Study - Generative > Load Case > Loads.

   Tip: To modify the applied load, do one of the following:
   • Mouse over it in the browser, and then click .
   • On the canvas, double-click the load glyph.

To apply a bearing load

1. On the Define tab, click Design Conditions > Structural Loads .

   The Structural Loads dialog opens.

2. Select the Bearing Load load from the drop-down list.

3. Select a cylindrical face or faces to place the load.

   Important: You can apply loads to preserve geometries only.

4. Choose the method of specifying the load direction.

   You can select one of the following methods:

   • Angle (delta) . Specify a relative X Angle, Y Angle, and Z Angle to orient the load direction. The Angle direction is relative to the first face selected for the load target. If you want to choose a different face, click Select in the Reference field and choose a reference face.
   • Vectors (x,y,z) . Specify the global force components:
     • Fx = X component
     • Fy = Y component
     • Fz = Z component
   • Reference . The direction is always radial, based on the selected cylindrical surface. Choose a reference entity to finalize the vector orientation, as follows:
     • Face (flat faces only): The vector direction is normal to the selected face.
     • Edge (straight edges only): The vector direction corresponds to the selected edge orientation.

5. (Optional) Click Flip Direction to reverse the load direction.
