DMPlexMetricEnforceSPD

Enforce symmetric positive-definiteness of a metric

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexMetricEnforceSPD(DM dm, Vec metricIn, PetscBool restrictSizes, PetscBool restrictAnisotropy, Vec metricOut, Vec determinant)

Input Parameters

• dm - The DM

• metricIn - The metric

• restrictSizes - Should maximum/minimum metric magnitudes be enforced?

• restrictAnisotropy - Should maximum anisotropy be enforced?

Output Parameters

• metricOut - The metric

Options Database Keys

• -dm_plex_metric_isotropic - Is the metric isotropic?

• -dm_plex_metric_uniform - Is the metric uniform?

• -dm_plex_metric_h_min - Minimum tolerated metric magnitude

• -dm_plex_metric_h_max - Maximum tolerated metric magnitude

• -dm_plex_metric_a_max - Maximum tolerated anisotropy
