FEM ConstraintPressure
Description
Applies a pressure load to a face.
Usage
- There are several ways to invoke the command:
- Press the
Pressure load button. - Select the Model → Mechanical boundary conditions and loads → Pressure load option from the menu.
- Press the
- Press the Add button and select face(s) in the 3D view. Optionally press the Remove and click on the faces that you want to remove from the selection.
- Edit the appropriate window to specify the pressure load in MPa.
- Tick the box to reverse the direction if necessary.
Notes
-
Distribution of the pressure on a face is always uniform and always perpendicular to the face.
-
{{VersionMinus|0.21}}: Pressure load can be applied to shells but only when Gmsh is used for meshing and group meshing is set to true. It is hardcoded as true so the user doesn\'t have to worry about that. However, due to a bug, pressure load may require remeshing to work on shells.
-
This feature uses the *DLOAD card in CalculiX.
