For a Fill+Pack analysis to be performed, at least one injection location must be specified. The injection location must be of the correct type. For example, a thermoplastics Fill+Pack analysis must be set using Analysis Set Injection Locations. For an Overmolding Fill+Pack analysis you need to set the Overmolding injection location for the second molding component using Analysis Set Overmolding Injection Locations. This error will occur if the process type has been changed after the injection location was specified.
