Description

Applies a pressure constraint to a face.

Usage

1. There are several ways to invoke the command:
   • Press the ConstraintPressure button.
   • Select the Model → Mechanical Constraints → Constraint pressure option from the menu.
2. Click on Add reference and select face in the [[3D view.
3. Edit appropriate window to specify pressure load in MPa.
4. Tick box to reverse direction if necessary.

Notes

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