DMStagSetUniformCoordinatesProduct

create uniform coordinates, as a product of 1D arrays

Synopsis

#include "petscdmstag.h"   
#include "petscdmproduct.h"   
PetscErrorCode DMStagSetUniformCoordinatesProduct(DM dm, PetscReal xmin, PetscReal xmax, PetscReal ymin, PetscReal ymax, PetscReal zmin, PetscReal zmax)

Set the coordinate DM to be a DMPRODUCT of 1D DMSTAG objects, each of which have a coordinate DM (also a 1d DMSTAG) holding uniform coordinates.

Collective

Input Parameters

• dm - the DMSTAG object

• xmin - minimum global coordinate value in the x direction

• xmax - maximum global coordinate value in the x direction

• ymin - minimum global coordinate value in the y direction

• ymax - maximum global coordinate value in the y direction

• zmin - minimum global coordinate value in the z direction

• zmax - maximum global coordinate value in the z direction

Notes

Arguments corresponding to higher dimensions are ignored for 1D and 2D grids.

The per-dimension 1-dimensional DMSTAG objects that comprise the product always have active 0-cells (vertices, element boundaries) and 1-cells (element centers).

See the manual page for DMStagSetUniformCoordinates() for information on how coordinates for dummy cells outside the physical domain boundary are populated.
