### 8.1.4. Postprocessing

Some of the most common plots to create in CFD-Post include:

- Mass Fractions: fuel, O2, products, intermediate species (CO), pollutants (NO)

- Turbulent Mixing Time Scale (Eddy Dissipation / Turbulent Kinetic Energy)

- Reaction Rates

  The variable "<my reaction>.Molar Reaction Rate" is available for every "Single Step" reaction (EDM, FRC or combined model).

- Plots of the turbulent Damköhler number (the ratio of the turbulent time scale to the chemical time scale)
