Defining coupled degrees of freedom

To couple the DOF of equivalently positioned nodes, use the Automatic Coupling command. Using the Automatic Coupling command:

• The software pairs the nodes on the independent side of the model with nodes on the dependent side of the model.

• The software searches for nodes based on the translation from a designated independent node to a designated dependent node using the search tolerance.

• Optionally, the software modifies the displacement coordinate system of all the nodes that participate in the coupling to use the designated coordinate system.

• You specify the directions and rotations in which the software couples the nodes.

For example, for a given node pair, the degrees of freedom of the first node becomes the independent and the second becomes the dependent.

For more information see, Automatic coupling.

To create a mesh with equivalently positioned nodes on the cyclic symmetric cut planes, use the 2D Dependent Mesh command.
