In this step, we define the inlet boundary as an ambient opening. To do this, we apply two conditions--an ambient pressure and an ambient temperature.
1. Click Boundary Conditions from the Setup tab:
2. Make sure all parts are visible by holding Ctrl and middle clicking anywhere off the model.
3. Left click on the inlet surface.
4. Click Edit from the Boundary Conditions context panel:
5. On the Type row, select Pressure.
6. Set the Unit to Pa and the Pressure value to 0.
7. Click Apply.
8. Click Setup (tab) > Selection (panel) > Select Previous.
9. Click Edit from the Boundary Conditions context panel:
10. On the Type row, select Temperature.
11. Verify the Units are Celsius. On the Temperature row, enter 25.
12. Click Apply.
What it should look like...
13. To verify that the two boundary conditions are properly assigned, check the Design Study Bar and the colored stripes on the inlet surface:
- a. On the Design Study bar, confirm the values for both conditions on the inlet surface. (Drag the right edge of the design study bar to see both conditions...)
- b. The two stripes on the inlet face should correspond to the boundary conditions types in the legend.
