Description
Applies a pressure constraint to a face.
Usage
- Click on
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
Limitations
Notes
