Class
    Foam::functionObjects::surfaceInterpolate

Group
    grpFieldFunctionObjects

Description
    Linearly interpolates volume fields to generate surface fields.

    Operands:
    \table
      Operand        | Type                  | Location
      input          | vol\<Type\>Field      | $FOAM_CASE/\<time\>/\<inpField\>
      output file    | -                     | -
      output field   | surface\<Type\>Field  | $FOAM_CASE/\<time\>/\<outField\>
    \endtable

    where \c \<Type\>=Scalar/Vector/SphericalTensor/SymmTensor/Tensor.

Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    surfaceInterpolate1
    {
        // Mandatory entries (unmodifiable)
        type        surfaceInterpolate;
        libs        (fieldFunctionObjects);

        // Mandatory entries (runtime modifiable)
        fields      ((<inpField1> <outField1>) ... (<inpFieldN> <outFieldN>));

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

    where the entries mean:
    \table
      Property     | Description                           | Type | Req'd | Dflt
      type         | Type name: surfaceInterpolate         | word |  yes  | -
      libs         | Library name: fieldFunctionObjects    | word |  yes  | -
      fields       | Names of operand and output fields    | wordList | yes | -
    \endtable

    The inherited entries are elaborated in:
     - \link functionObject.H \endlink

    Usage by the \c postProcess utility is not available.
