In early versions of OpenFOAM the scalar limits were simple macro replacements and the
names were capitalized to indicate this. The scalar limits are now static
constants which is a huge improvement on the use of macros and for consistency
the names have been changed to camel-case to indicate this and improve
readability of the code:
GREAT -> great
ROOTGREAT -> rootGreat
VGREAT -> vGreat
ROOTVGREAT -> rootVGreat
SMALL -> small
ROOTSMALL -> rootSmall
VSMALL -> vSmall
ROOTVSMALL -> rootVSmall
The original capitalized are still currently supported but their use is
deprecated.
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;
}
}
}
