The DEFAULT species model for the project needs to be set in the models configuration file (.cfg). For more information on the models configuration file, please see What is a configuration file?.

Any other units will use the species model of its inlet streams. • To set the species model in the Feeder or the Makeup Source, under the Contents tab page, select the modeltype. If a species model is selected, then (Reqd) will appear after the word Model as a reminder that the user has manually set the species model. If the user wants to set the species model back to its default, then Inherit should be chosen, when this happens, (heritage) will appear after the word Model as a reminder that the species model is determined by SysCAD. • In the case of two different species model entering the same unit operation, SysCAD will decide what to use for its outlets. In these cases, the user can manually set the species
