** ERROR 1100437 ** More than one injection node is found. Feed system cannot be designed if more than one injection node is defined.
Explanation
The Runner Balance analysis requires the full runner system (sprue, runners and gates) to be modeled. There should be only one injection location set at the top of the sprue.
Resolution
Model the full runner system, either manually or using the Runner System Wizard in the Modeling menu, then set the injection location at the top of the sprue.
