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.
