# 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 object created is an hybrid mesh, the vertex ordering in the cone of the cell is that of the prismatic cells
