I am trying to obtain total enthalpy values of my finite rate combustion simulations. I tried using the C_H(c,t) macro, but it retrieves sensible enthalpy values and not total enthalpy values. How do I access the total enthalpy values, either through some computation within the UDF or through a macro?
( if it is even possible)

You may have to add enthalpy of formation to that. You can use PROP_href or PROP_hform to fetch this within a UDF. Look at UDF example that uses species loop.
