Constraint transform

Ограничение перемещения

FEM

Описание

Creates a FEM boundary condition for a fixed geometrical entity by locking all the available degrees of freedom (DOFs) of the nodes underlying the selected geometrical entity (6 DOFs for beam and shell elements, 3 for solid elements).

Применение

1. 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.
2. Press the Add button.
3. In the 3D view select the object the boundary condition should be applied to, which can be a vertex, edge, or face (but all objects have to be of the same type). To remove objects from the selection, press the Remove button and click on them.

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.
