enum | Possibilities { no_refinement = 0, cut_x = 1, cut_y = 2, cut_xy = cut_x | cut_y, isotropic_refinement = cut_xy } |
A class that provides possible choices for isotropic and anisotropic refinement flags in the current space dimension.
This specialization is used for dim=2
, where it offers refinement in x- and y-direction separately, as well as isotropic refinement in both directions at the same time.
enum RefinementPossibilities< 2 >::Possibilities |
Possible values for refinement cases in the current dimension.
Note the construction of the values: the lowest bit describes a cut of the x-axis, the second to lowest bit corresponds to a cut of the y-axis and the third to lowest bit corresponds to a cut of the z-axis. Thus, the following relations hold (among others):
Only those cuts that are reasonable in a given space dimension are offered, of course.
In addition, the tag isotropic_refinement
denotes isotropic refinement in the space dimension selected by the template argument of this class.
