Add Constraints and Loads

To define constraints and loads, use the commands available in the ribbon panels. Alternatively, right-click the browser node for the input type, and click the command there.

1. On the ribbon, click Stress Analysis tabConstraints panel Fixed.

   The dialog box displays with the Face selector active.

2. Choose the appropriate faces. Multiple faces can be selected. In this case, the faces represent a rigid attachment that occurs later in the manufacturing process.
   
3. Click OK to complete the constraint inputs.

Add the second constraint:

1. Click the Fixed command.
2. Select the cylindrical faces of the slot feature.
   
3. Click OK.

Next, we add a force or load. These steps define a condition where the assembly receives a constant load in a given direction.

1. Click Stress Analysis tabLoads panel Force.

   The dialog box displays.

2. Choose the flat face at the bolt head.
3. Click the More command to expand the dialog box, and check Use Vector Components.
4. For the Fz component, enter 225. It defines the force magnitude and direction.
   
5. Click OK.

We now have defined materials, structural load, and constraints. In the browser, expand the Constraints and Loads nodes for viewing. Click a node to highlight the selection or location in the graphics window; and double-click to edit the definition.
