Pressure Loads—Creo Ansys Simulation
You can create pressure loads in your model. A positive pressure load always acts opposite to the normal direction of the surface at every location, even if the surface is curved.
To Define a Pressure Load
1. Within a structural simulation study, click > 
Pressure. The Pressure Load dialog box opens.
Pressure. The Pressure Load dialog box opens.2. Specify a name for the load, or use the default name. Optionally click the color swatch adjacent to the Name box to change the color of the icon, the distribution, or the text displayed for the load.
3. Select the reference to which you want to apply a pressure load. Your selection appears in the References collector.
4. Enter a real number, arithmetic expression, or parameter name for the value of pressure in the Magnitude field.
5. Select units of pressure from the list or accept the default units.
6. Click OK to create the load and save it.
