** ERROR 305554 ** The valve gate controller(s) listed below are not connected to any part or cold runner element. Please review the valve gate property assignment in the model and ensure every group reaches a part or cold runner element.
This configuration is invalid because none of the hot gate elements assigned to a valve gate controller is connected to a part element or a cold runner element. Hot gate elements with a valve gate controller must connect to part elements or cold runner elements downstream.
Review the valve gate property assignment for the valve gate controller(s) listed in the error message. Ensure that every group assigned to a valve gate controller reaches a part or cold runner element. Rerun the analysis.
