Is it possible to use the temperature calculated from a surface goal of an outlet boundary as the fluid temperature of an inlet boundary? I am trying to simulate a coolant line that is a closed system. as the temperature increases throughout the system, the inlet temperature needs to be the same as the outlet temperature. For context, I have a subdomain where there is a separation due to a lid. On one face of the lid I have the outlet boundary and the other side has the inlet boundary. Any help would be muchly appreciated.
