DMPlexCreateEphemeral

This takes a DMPlexTransform and a base DMPlex and produces an ephemeral DM, meaning one that is created on the fly in response to queries.

Synopsis

#include "petscdmplex.h"   
#include "petscdmplextransform.h"   
PetscErrorCode DMPlexCreateEphemeral(DMPlexTransform tr, const char prefix[], DM *dm)

Input Parameters

• tr - The DMPlexTransform

• prefix - An options prefix, or NULL

Output Parameter

• dm - The DM

Notes

An emphemeral mesh is one that is not stored concretely, as in the default DMPLEX implementation, but rather is produced on the fly in response to queries, using information from the transform and the base mesh.
