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.
