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.
- Click on Add 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 the pressure on a face is always uniform and always perpendicular to the face.
- Currently, 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 in recent versions so the user doesn't have to worry about that. However, due to a bug, pressure load may require remeshing to work.
- This feature uses the *DLOAD card in CalculiX. It is described at https://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node190.html
