Applies a pressure constraint to a face.

Press the button or choose Model → Mechanical Constraints → Constraint pressure‏‎ from the top menu.
Click on Add reference and select face in 3D view.
Edit appropriate window to specify pressure load in MPa.
Tick box to reverse direction if necessary.

Distribution of pressure on face is always uniform and always perpendicular to face.
