Class
    Foam::fv::patchCellsSource

Group
    grpFvOptionsSources

Description
    Source defined by a boundary condition applied to cells next to patches.
    This fvOption needs to be used with a \c boundarySourcePatch type of
    boundary condition (e.g. \c speciesSorption and \c enthalpySorption.)

Usage
    Minimal example by using \c constant/fvOptions:
    \verbatim
    <fvOptionName>
    {
        // Mandatory entries
        type        patchCellsSource;

        // Optional entries (one only!)
        U           <word>;
        he          <word>;
        species     <word>;

        // Inherited entries
        ...
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                       | Type   | Reqd | Deflt
      type      | Type name: patchCellsSource       | word   | yes  | -
      U         | Name of operand velocity field    | word   | choice | -
      he        | Name of operand energy field      | word   | choice | -
      species   | Name of operand species field     | word   | choice | -
    \endtable

    The inherited entries are elaborated in:
