DMPlexMetricCreateIsotropic#

Construct an isotropic metric from an error indicator

Synopsis#

#include "petscdmplex.h"   
PetscErrorCode DMPlexMetricCreateIsotropic(DM dm, PetscInt f, Vec indicator, Vec *metric)

Input Parameters#

  • dm - The DM

  • f - The field number to use

  • indicator - The error indicator

Output Parameter#

  • metric - The isotropic metric

Notes#

It is assumed that the DM is comprised of simplices.

The indicator needs to be a scalar field. If it is not defined vertex-wise, then it is projected appropriately.
