Class
    Foam::outletMappedUniformInletFvPatchField
 
Group
    grpInletBoundaryConditions
 
Description
    The \c outletMappedUniformInlet is an inlet boundary condition that
    - averages the patch field of <Type> over a specified "outlet" patch
    and uniformly applies the averaged value over a specified inlet patch.
    - optionally, the averaged value can be scaled
    and/or offset by a pair of specified values.
 
    The governing equation of the boundary condition is:
 
    \f[
        \phi_{inlet} = f \phi_{outlet} + \phi_{offset}
    \f]
 
    where
    \vartable
      \phi_{inlet}   | Spatially-uniform patch-field value at an inlet patch
      \phi_{outlet}  | Averaged patch-field value at an outlet patch
      f              | User-defined fraction value
      \phi_{offset}  | User-defined offset value
    \endvartable
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries (unmodifiable)
        type            outletMappedFilterInlet;
        outletPatch     <outletPatchName>;
 
        // Optional entries (unmodifiable)
        fraction        0.1;
        offset          10;    // (1 0 0);
        phi             phi;
 
        // Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property    | Description                          | Type   | Reqd | Dflt
      type        | Type name: outletMappedUniformInlet  | word   | yes  | -
      outletPatch | Name of patch to be mapped           | word   | yes  | -
      fraction    | Fraction value                       | scalar | no   | 1
      offset      | Offset value                         | Type   | no   | Zero
      phi         | Name of operand flux field           | word   | no   | phi
    \endtable
 
    The inherited entries are elaborated in:
