Описание
Creates a FEM boundary condition for a fixed geometrical entity by locking all the available degrees of freedom of the nodes underlying the selected geometrical entity (6 DOFs for beam and shell elements, 3 for solid elements).
Применение
- There are several ways to invoke the command:
- Press the Fixed boundary condition button.
- Select the Model → Mechanical boundary conditions and loads → Fixed boundary condition option from the menu.
- In the 3D view select the object the boundary condition should be applied to, which can be a vertex (corner), edge, or face.
Ограничения
You cannot mix object types within the same boundary condition. Use a separate fixed boundary condition for each object type.
Notes
- This feature uses the *BOUNDARY card in CalculiX.
