Class
    Foam::PatchFunction1Types::UniformValueField
 
Description
    Templated function that returns a uniform field based on a run-time
    selectable Function1 entry.
 
    Usage - for entry <entryName> returning the value <value>:
    \verbatim
        <entryName>    uniformValue
    \endverbatim
