Cartesian coordinates of point i of the polyhedron. Name of the point. Global maximum tetrahedra size in model. Real, default is 0.0. When this value is non-zero the mesher will try to resolve geometric detail by using smaller and smaller elements.
Smaller values imply coarser meshes.
The default value is .2 . For a perfect model the value could approach 0.0. This value is used to determine if an edge is intersected by a surface. Otherwise the intersection will be used to split the edge. Real, default is 0.0.
