Class
    Foam::fv::limitTemperature

Group
    grpFvOptionsCorrections

Description
    Corrects temperature field (i.e. \c T) within a specified
    region by applying limits between a given minimum and maximum.

    Corrections applied to:
    \verbatim
      T    | Temperature                   [K]
    \endverbatim

    Required fields:
    \verbatim
      T    | Temperature                   [K]
      e/h  | Internal energy/Enthalphy     [m2/s2]
    \endverbatim

Usage
    Minimal example by using \c constant/fvOptions:
    \verbatim
    limitTemperature1
    {
        // Mandatory entries (unmodifiable)
        type            limitTemperature;

        // Mandatory entries (runtime modifiable)
        min             <minValue>;
        max             <maxValue>;

        // Optional entries (runtime modifiable)
        phase           <phaseName>;

        // Mandatory/Optional (inherited) entries
        ...
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                   | Type   | Reqd  | Dflt
      type      | Type name: limitTemperature   | word   | yes   | -
      min       | Minimum temperature limit [K] | scalar | yes   | -
      max       | Maximum temperature limit [K] | scalar | yes   | -
      phase     | Name of operand phase field   | word   | no    | ""
    \endtable

    The inherited entries are elaborated in:
      - \link fvOption.H \endlink
      - \link cellSetOption.H \endlink
      - \link writeFile.H \endlink
