Hi Engineers,

Does anyone know or have any ideas in specifying flow sequence in Fired Hetaer (with HYSYS EDR model)?

I built a rigorous fired heater model with ASPEN HYSYS, I am unable to add a new stream to the model. When I had the model solved using the first stream in the radiant section, in trying to add a new stream via the Convection Section I'm getting an error message from my EDR saying "The specified flow sequence, through convection banks and/or the fire box is inconsistent"

Thanks in advance for your help.
