Class
    Foam::CONSTRUCT

Group
    grpGenericBoundaryConditions

Description
    This boundary condition provides a NAME condition,
    calculated as:

        \f[
            Q = Q_{0} + Q_{p} + s*Q_{t}
        \f]

    where
    \vartable
        s      | single scalar value [units]
        Q_{0}  | single TYPE value [units]
        Q_{p}  | TYPE field across patch [units]
        Q_{t}  | TYPE function of time [units]
    \endtable

Usage
    \table
        Property   | Description                  | Req'd | Default
        scalarData | single scalar value          | yes |
        data       | single TYPE value          | yes |
        fieldData  | TYPE field across patch    | yes |
        timeVsData | TYPE function of time      | yes |
        wordData   | word, eg name of data object | no  | wordDefault
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type       NAME;
        scalarData -1;
        data       ONE;
        fieldData  uniform THREE;
        timeVsData table (
                             (0 ZERO)
                             (1 TWO)
                          );
        wordName   anotherName;
        value      uniform FOUR; // optional initial value
    }
