Description
Applies a pressure constraint to a face.
Usage
- There are several ways to invoke the command:
- Press the
FEM ConstraintPressure button.
- Select the Model → Mechanical Constraints →
Constraint pressure option from the menu.
- Press the
- Click on Add reference and select face in the 3D view.
- Edit appropriate window to specify pressure load in MPa.
- Tick box to reverse direction if necessary.
Notes
- Distribution of pressure on face is always uniform and always perpendicular to face.
