43b35a5173 triangle, triFace, face: Rationalized normal for consistency with the rest of OpenFOAM 
For compatibility with all the mesh and related classes in OpenFOAM The 'normal'
function of the 'triangle', 'triFace' and 'face' classes now returns the unit
normal vector rather than the vector area which is now provided by the 'area'
function.

3e761d6a41 foamyHexMesh: Added cell sizing based on local surface closeness 
First run the surfaceFeatureExtract with the "closeness" option enabled in the
surfaceFeatureExtractDict to extract the surface closeness point field

    // Out put the closeness of surface elements to other surface elements.
    closeness               yes;

Then enable cell sizing based on local surface closeness by specifying the
"internalCloseness" options in the foamyHexMeshDict e.g.

motionControl
{
    defaultCellSize             4;

    minimumCellSizeCoeff        0.1;
    maxSmoothingIterations      100;
    maxRefinementIterations     2;

    shapeControlFunctions
    {
        geometry
        {
            type                        searchableSurfaceControl;
            priority                    1;
            mode                        inside;

            surfaceCellSizeFunction     nonUniformField;

            cellSizeCalculationType     automatic;

            curvature                   false;
            curvatureFile               dummy;
            featureProximity            false;
            featureProximityFile        dummy;
            internalCloseness           true;
            internalClosenessFile       geometry.internalPointCloseness;
            internalClosenessCellSizeCoeff 25;
            curvatureCellSizeCoeff      0;
            maximumCellSizeCoeff        1;
            cellSizeFunction            uniform;
        }
    }
}
