Description

Applies a pressure constraint to a face.

Usage

  1. There are several ways to invoke the command:
    • Press the FEM 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.
