To Define Pressure Loads—Topology Optimization
1. Click Home > Loads > Pressure. The Pressure Load dialog box opens.
2. Enter a name for the load, or use the default name. Click the color swatch next to Name if you want to change the color of the constraint icon.
3. Select an existing load set from the Member of Set area or click New to create a new load set.
4. If you did not select a geometric reference before opening the Pressure Load dialog box, select the entity now. The References collector shows the selected entities.
5. If you want to specify how the load is distributed across the selected geometry, click the Advanced button and select one of the following options from the Spatial Variation drop-down list:
Uniform
Function Of Coordinates
Interpolated Over Entity
At any time, you can select or clear the selection of surfaces manually.
6. Enter a real number, arithmetic expression, or parameter name for the pressure load in the Value field. Select units of pressure from the drop-down list or accept the default units.
7. Click OK to accept and save the load.
If problems with the definition of the load are identified, a message appears.
If there are no problems with the definition, then the loads are applied to the selected entities. A load icon is added to the selected geometry.
For details about loads, see the Creo Simulate help.
