PetscErrorCode DMPlexMetricCreate(DM dm, PetscInt f, Vec *metric)
Input Parameters#
dm - The
DMf - The field number to use
Output Parameter#
metric - The metric
Options Database Key#
-dm_adaptor <pragmatic/mmg/parmmg> - specify dm adaptor to use
Options Database Keys for Mmg and ParMmg#
-dm_plex_metric_gradation_factor - Maximum ratio by which edge lengths may grow during gradation
-dm_plex_metric_num_iterations - Number of parallel mesh adaptation iterations for ParMmg
-dm_plex_metric_no_insert - Should node insertion/deletion be turned off?
-dm_plex_metric_no_swap - Should facet swapping be turned off?
-dm_plex_metric_no_move - Should node movement be turned off?
-dm_plex_metric_verbosity - Choose a verbosity level from -1 (silent) to 10 (maximum).
Options Database Keys for Riemannian metrics#
-dm_plex_metric_isotropic - Is the metric isotropic?
-dm_plex_metric_uniform - Is the metric uniform?
-dm_plex_metric_restrict_anisotropy_first - Should anisotropy be restricted before normalization?
-dm_plex_metric_h_min - Minimum tolerated metric magnitude

-dm_plex_metric_p - L-p normalization order
-dm_plex_metric_target_complexity - Target metric complexity
Note#
It is assumed that the DM is comprised of simplices.
