Class
    Foam::enthalpySorptionFvPatchScalarField

Group
    grpGenericBoundaryConditions

Description
    This is a temperature boundary condition which works
    in conjunction with the \c speciesSorption condition for species.

    This boundary condition substracts or adds enthalpy associated with the
    adsorption provided by the \c speciesSorption condition.

    It can handle two enthalpy models:

    1) Estimate
    2) Calculated

    On top of this, the enthalpy associated with the sensible enthalpy
    corresponding with the species transport can be added using \c includeHs.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        type                enthalpySorption;
        enthalpyModel       <word>;
        species             <word>;

        // Conditional mandatory entries

        // when enthalpyModel == calculated
        enthalpyTable       <Function1<scalar>>

            // enthalpyTable
            // {
            //     type            table;
            //     values          ((0 0)(1 50));
            // }

        // Optional entries
        includeHs           <bool>;
        C                   <scalar>;
        Hvap                <scalar>;
        dhdt                <scalarField>;
        p                   <word>;
        T                   <word>;
    }
    \endverbatim

    where the entries mean:
    \table
      Property | Description                        | Type   | Reqd   | Deflt
      type     | Type name: enthalpySorption        | word   | yes    | -
      enthalpyModel | Adsorption enthalpy model     | word   | yes    | -
      species  | Name of associated species         | word   | yes    | -
      enthalpyTable | Calculated enthalpy model table       <!--
               -->                         | Function1<scalar> | no | -
      includeHs | Include sensible enthalpy         | bool   | no     | true
      C        | Estimate enthalpy model constant   | scalar | no     | 0
      Hvap     | Evaporation heat for species       | scalar | no     | 0
      p        | Name of operand pressure field     | word   | no     | p
      T        | Name of operand temperature field  | word   | no     | T
      dhdt     | Enthalpy change on cells next to patch [J/kg]       <!--
               -->                             | scalarField | no     | Zero
    \endtable

    Options for the \c enthalpyModel entry:
    \verbatim
      estimated    | Enthalpy is estimated
      calculated   | Enthalpy is calculated based on enthalpyTable
    \endverbatim

    The inherited entries are elaborated in:

      - \link Function1.H \endlink
