Interface temperature

hello sir,
in conjugate heat transfer problem i created two separate domains in ICEM CFD
and i have made interface between them in CFX(as shown in attached image)
in solver output monitor plot when i plot AVERAGE temperature of interface surfaces both gives different values
i.e areaAve(T)@inter_fluid and areaAve(T)@inter_solid
i an unable to get why CFX plotting different values

Thank you sir

You get different temepratures because it is using the control volumes which have a centroid a small distance off the interface. So you are comparing the temperature a small distance into the fluid domain with the temperature a small distance into the solid domain.
