# 4.13.3. Averaging

The averaging block in the `Fuego Region` lets you calculate Reynolds and Favre averages of any nodal field, as well as provides post-processors for modeled and resolved turbulent quantities.

    BEGIN AVERAGING
        REYNOLDS AVERAGE FIELD temperature AS reynolds_temperature
        REYNOLDS AVERAGE FIELD pressure    AS reynolds_pressure
        REYNOLDS AVERAGE FIELD radiative_flux AS reynolds_rad_flux
        FAVRE AVERAGE FIELD    temperature AS favre_temperature
        FAVRE AVERAGE FIELD    pressure    AS favre_pressure
        FAVRE AVERAGE FIELD    radiative_flux AS favre_rad_flux
        TIME INTERVAL LENGTH IS  2.0
        STARTING TIME IS         2.0

        Compute resolved_reynolds_stress
        Compute resolved_favre_stress
        Compute resolved_turbulent_kinetic_energy
        Compute resolved_production
        Compute resolved_dissipation
        Compute resolved_scalar_flux of enthalpy
        Compute modeled_reynolds_stress
        Compute modeled_scalar_flux of enthalpy
    END AVERAGING

Note

The filter is reset after it reaches the `time interval length` and starts over again. Filtered values just after that point will not have been averaged over a very long time window yet. To get a continuously averaged quantity, use the `Moving Average Filtered Field` with the `Moving Average Time`

The complete list of commands for the averaging block can be found in the command summary.

## 4.13.3.1. Pre-Defined Quantities

You can use the `Compute` command to compute several pre-defined quantities, described in the command summary.
