Hello everyone,

I am writing a UDF source code for Energy equation where I have to include species enthalpy but I am not sure how. There is a cell macro for enthalpy C_H(c,t) , but I am interested in finding species' enthalpy. Could someone please help me out with this?

That will be the mixture enthalpy. What do you mean by species enthalpy?

Best regards, Amine

My mixture has O2, N2, H2, H2O, CH4..and many other species, how to find the enthalpy of each species in a cell rather than the whole mixture enthalpy.  I believe the mixture enthalpy is related to species enthalpy through the equation below. So basically I am interested in hi
