Using the Notification Center
When you regenerate and open a part in Creo Simulate, features and objects that fail during regeneration are displayed in the Notification Center. You can view the details of the failed part, feature or object in the Notification Center.
Depending on why a simulation object or feature has failed, the following states are displayed in the Feature Status column in the Model Tree:
• Failed
—Indicates failure to regenerate a component or feature in a part or assembly.
—Indicates failure to regenerate a component or feature in a part or assembly.• Suppressed—Indicates that the feature or object has been suppressed. Select the parent of the object or feature in the Model Tree and click > > 
Resume if you want the feature or object to be a part of the model.
Resume if you want the feature or object to be a part of the model.• Out of Session
—Indicates that a simulation object or feature is not active for the current session. For example, if an assembly contains a part that has a gravity load or any other body load applied to it, the body load displays an “Out of Session” status in the Model Tree for the assembly.

For example, if an assembly contains a part that has a gravity load or any other body load applied to it, the body load displays an “Out of Session” status in the Model Tree for the assembly. | To activate the Feature Status column in the Model Tree, click  Model Tree > and select Feature Status from the Model Tree Columns dialog box. |
To identify, locate and fix an error, click 
below the graphics window and then click Open Notification Center. The Notification Center dialog box opens. You can now edit and fix the failed object or feature from the Notification Center. In the Notification Center dialog box, drill down to the failed simulation feature.
