PetscErrorCode DMPlexMetricSetHausdorffNumber(DM dm, PetscReal hausd)
Input parameters#
dm - The
DMhausd - The metric Hausdorff number
Notes#
The Hausdorff number imposes the maximal distance between the piecewise linear approximation of the boundary and the reconstructed ideal boundary. Thus, a low Hausdorff parameter leads to refine the high curvature areas. By default, the Hausdorff value is set to 0.01, which is a suitable value for an object of size 1 in each direction. For smaller (resp. larger) objects, you may need to decrease (resp. increase) the Hausdorff parameter.
