+ // boundary conforming.
+ // Also used to as the grid spacing usind in insertGrid.

+ // Feature angle used to inser feature points
+ // 0 = all features, 180 = no features
+ featureAngle 45;
+
+ // Maximum quadrant angle allowed at a concave corner before
+ // additional "mitering" lines are added
+ maxQuadAngle 110;
+
+ // Should the mesh be square-dominated or of unbiased hexagons
+ squares yes;
+
+ // Near-wall region where cells are aligned with the wall specified as a
+ // number of cell layers
+ nearWallAlignedDist 3;
+

+ // or remain fixed to the x-y directions

+ // Number of relaxation iterations.
+ nIterations 5;

+ // 0.5 is a sensible maximum and < 0.2 converges better.
+ relaxationFactorStart 0.8;
+
+ // Relaxation factor at the end of the iteration sequence.
+ // Should be <= relaxationFactorStart
+ relaxationFactorEnd 0;
+

+ Foam::backgroundMeshDecomposition
+
+Description
+ Store a background polyMesh to use for the decomposition of space and
+ queries for parallel conformalVoronoiMesh.
+
+ The requirements are:
+
+ + To have a decomposition of space which can quickly interrogate an
+ arbitrary location from any processor to reliably and unambiguously
+ determine which processor owns the space that the point is in, i.e. as
+ the vertices move, or need inserted as part of the surface conformation,
+ send them to the correct proc.
+
+ + To be able to be dynamically built, refined and redistributed to other
+ procs the partitioning as the meshing progresses to balance the load.
+
+ + To be able to query whether a sphere (the circumsphere of a Delaunay tet)
+ overlaps any part of the space defined by the structure, and whether a
+ ray (Voronoi edge) penetrates any part of the space defined by the
+ structure, this is what determines if points get referred to a processor.

+ Abstract base class for providing faceAreaWeight values to the cell motion
