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.
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
