Total enthalpy calculation

Hello I´m simulating a system where I want to know the inlet specific entalphy, the fluid is water so Cp=4186 J/kg*K. With the boundary probe Comsol gives me the values I´m looking for but I want to be sure they are correct. I know the temperature of the inflow is 298.15 K and the result of the total enthalpy is 101.51 J/kg. For the entaplhy I used this expression "ht2.H0" which Comsol says it´s "Total enthalpy". Can someone tell me how does Comsol calculate values with this expression? I thought that, in first approximation, dh=cp * dt but the results are not the same. Thank you for your help
