ustbdynamic Member xingangzheng Join Date: Jul 2009 Posts: 40 Rep Power: 17	hi all, I'm simulating a flow problem inferring multicomponent species. During this fluid flow, some species will be consumed (That is to say existing sink term). When simulating the energy source, this requires the enthalpy of the corresponding component. But it seems hard to get this value from UDF. An alternative method, I can use this formulation to calculate. H(T)=H(Tref)+∫Cp(T)dT But the value of enthalpy at reference temperature (H(Tref)) still needs to be known or obtained by UDF. does anyone know how to solve it? thanks
