Setting nodal constraints

You may want to set further constraints to simulate the constraints on the part when in use, for example, areas of the part that are fixed to another object.

1. If the model nodes are not visible, turn on the appropriate layer in the Layers pane.
2. If you want to use a local coordinate system when setting constraints, first define and activate the local coordinate system.
3. Click one of the sub-menu items under (Boundary Conditions tab > Constraints and Loads panel > Constraints).
4. Use the cross-hairs to select the node(s) for which you want to set the constraint.
   • If you are setting a Spring constraint, enter the required Transitional stiffness and Rotational stiffness values in the X, Y, and Z directions.
   • If you are setting a General constraint, specify for each of the X, Y, and Z directions whether the translational or rotational degree of freedom at the node(s) should be Free, Fixed, or set to a specified distance or angle.
5. Click Apply in the Set Constraints dialog or right-click in the model pane and select Apply. An appropriate constraint symbol will be displayed at each node you have constrained.
6. Once you have finished applying constraints, right-click in the model pane and select Finish Constraints.

Note: Now that you have successfully set the model constraint(s) in order to prevent rigid body motion, you can now apply the required load(s) to the model.
