Class
    Foam::sampledPatchInternalField
 
Description
    Variation of sampledPatch that samples the internalField (at a given
    normal distance from the patch) instead of the patchField.
    Note:
    - interpolate=false : get cell value on faces
    - interpolate=true  : interpolate inside cell and interpolate to points
    There is no option to get interpolated value inside the cell on the faces.
 
    This is often embedded as part of a sampled surfaces function object.
 
Usage
    Example of function object partial specification:
    \verbatim
    surfaces
    {
        surface1
        {
            type    patchInternalField;
            patches (inlet "outlet.*");
            offsetMode  normal;
            distance    0.05;
        }
    }
    \endverbatim
 
    Where the sub-entries comprise:
    \table
        Property | Description                             | Required | Default
        type     | patchInternalField                      | yes      |
        patches  | patch selection as word/regex list      | yes      |
        offsetMode | normal/uniform/nonuniform             | no       | normal
        distance | distance for normal offset              | partly   |
        offset   | point offset for uniform offset         | partly   |
        offsets  | point offsets for nonuniform offset     | partly   |
    \endtable
