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;
}
}
