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.

  • 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.
