DMPlexExtrude

Creates a (d+1)-D mesh by extruding a d-D mesh in the normal direction using prismatic cells.

Synopsis

#include "petscdmplex.h"   
#include "petscdmplex.h"   
PetscErrorCode DMPlexExtrude(DM idm, PetscInt layers, PetscReal height, PetscBool ordExt, PetscBool interpolate, DM* dm)

Collective on idm

Input Parameters

	idm	- The mesh to be extruted
	layers	- The number of layers
	height	- The height of the extruded layer
	ordExt	- If PETSC_TRUE, orders the extruded cells in the height first. Otherwise, orders the cell on the layers first
	interpolate	- Flag to create intermediate mesh pieces (edges, faces)

Output Parameter

dm -The DM object

Notes: The mesh created has prismatic cells, and the vertex ordering in the cone of the cell is that of the tensor prismatic cells.
