Class
    Foam::functionObjects::turbulenceFields

Group
    grpFieldFunctionObjects

Description
    This function object stores turbulence fields on the mesh database for
    further manipulation.

    Fields are stored as copies of the original, with the prefix
    "tubulenceModel:", e.g.:

    \verbatim
    turbulenceModel:R
    \endverbatim

    Example of function object specification:
    \verbatim
    turbulenceFields1
    {
        type        turbulenceFields;
        libs ("libfieldFunctionObjects.so");
        ...
        fields
        (
            R
            devRhoReff
        );
    }
    \endverbatim

    \heading Function object usage
    \table
        Property     | Description                 | Required | Default value
        type         | type name: processorField   | yes      |
        fields       | fields to store (see below) | yes      |
    \endtable

    Where \c fields can include:
    \plaintable
        k           | turbulence kinetic energy
        epsilon     | turbulence kinetic energy dissipation rate
        omega       | turbulence specific dissipation rate
        nut         | turbulence viscosity (incompressible)
        nuEff       | effective turbulence viscosity (incompressible)
        mut         | turbulence viscosity (compressible)
        muEff       | effective turbulence viscosity (compressible)
        alphat      | turbulence thermal diffusivity (compressible)
        alphaEff    | effective turbulence thermal diffusivity (compressible)
        R           | Reynolds stress tensor
        devReff     | Deviatoric part of the effective Reynolds stress
        devRhoReff  | Divergence of the Reynolds stress
    \endplaintable
