Class
    Foam::mappedValueFvPatchField
 
Description
    This boundary condition maps the values from a neighbouring patch to this
    patch.
 
Usage
    \table
        Property     | Description                | Required | Default value
        field        | name of field to be mapped | no       | this field name
        setAverage   | set the average value?     | no       | yes if average \\
                                                               is specified, \\
                                                               no otherwise
        average      | average value to apply     | if setAverage is true |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            mappedValue;
        field           T;
        average         300;
        value           uniform 300;
    }
    \endverbatim
 
    This boundary condition will usually be applied to a patch which is of
    mappedPatchBase type, and which holds all the necessary mapping
    information. It can also create its own mapping data which overrides that
    in the mapped patch, or so that it can be applied to a non-mapped patch.
    This is triggered by the presence of controls relating to mappedPatchBase
    (i.e., neighbourRegion, neighbourPatch, etc ...).
