PetscErrorCode DMPlexMetricCreate(DM dm, PetscInt f, Vec *metric)
Input Parameters#
- dm - The - DM
- f - 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?
