DMPlexTransformCellTransformIdentity

Default celltransform implementation for transforms that reproduce the input mesh

Synopsis

#include "petscdmplextransform.h" 
PetscErrorCode DMPlexTransformCellTransformIdentity(DMPlexTransform tr, DMPolytopeType source, PetscInt p, PetscInt *rt, PetscInt *Nt, DMPolytopeType *target[], PetscInt *size[], PetscInt *cone[], PetscInt *ornt[])

Not Collective

Input Parameters

• tr - The DMPlexTransform

• source - The cell type of the source point

• p - The source point

Output Parameters

• rt - Refinement type of the source point (set to 0), or NULL

• Nt - Number of target cell types produced (always 1)

• target - Array of produced cell types (a single-element array containing source)

• size - Array of replica counts for each produced type (a single-element array containing 1)

• cone - Cone description used by DMPlexTransformGetCone(); encodes that the replica takes the entire parent cone

• ornt - Orientation array associated with cone; all zero for identity

Note

This routine returns statically allocated arrays describing an identity refinement for each supported DMPolytopeType; every source point produces a single replica of the same type with unchanged cone and orientation.
