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.
