Group
    grpInletBoundaryConditions
 
Description
    The \c outletMappedUniformInlet is an inlet boundary condition that
    - averages patch fields of specified "outlet" patches
    and uniformly applies the averaged value over a specified inlet patch.
    - optionally, the averaged value can be scaled
    and/or offset by a specified value,
    and/or mapped by a specified time delay.
 
    The governing equation of the boundary condition is:
 
    \f[
        \phi_{inlet} =
            \sum_i \left( f_i \phi_{{outlet}_i} + \phi_{{offset}_i} \right)
    \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
      i              | Outlet-patch index
    \endvartable
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        type            outletMappedUniformInlet;
 
        outlets
        {
            <outletName.1>
            {
                fraction    <Function1<scalar>>;
                offset      <Function1<Type>>;
                timeDelay   <Function1<scalar>>;
            }
            <outletName.2>
            {
                fraction    <Function1<scalar>>;
                offset      <Function1<Type>>;
                timeDelay   <Function1<scalar>>;
            }
            ...
        }
 
        // Optional entries
        uniformValue    <PatchFunction1<Type>>;
        phi             phi;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property    | Description                          | Type   | Reqd | Deflt
      type        | Type name: outletMappedUniformInlet  | word   | yes  | -
      outlets     | Dictionary name: outlets             | dict   | yes  | -
      fraction    | Fraction value          | Function1<scalar> | no   | 1
      offset      | Offset value            | Function1<Type>   | no   | Zero
      timeDelay   | Time delay              | Function1<scalar> | no   | 0
      uniformValue | Base inlet patch field | PatchFunction1<Type> | no | Zero
      phi         | Name of operand flux field           | word   | no   | phi
    \endtable
 
    The inherited entries are elaborated in:
      - \link fixedValueFvPatchFields.H \endlink
      - \link PatchFunction1.H \endlink
      - \link Function1.H \endlink
 
Note
  - Any negative input of \c timeDelay entry
    is forced to be zero without emitting any warnings.
