Frans D Guest Posts: n/a	Hi All, I am trying to model a batch chemical reaction. I have one idea to do it but don't know how to start. I thought of getting the compound mass fractions from the outlet at one time step and specify them for the inlet stream for the next time step. I was thinking of writing a UDF for this but I do not know the macro to extract the mass fractions at the outlet stream. Many thanks. Frans
