# 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.
