DMStagSetUniformCoordinatesExplicit#
set DMSTAG
coordinates to be a uniform grid, storing all values
Synopsis#
PetscErrorCode DMStagSetUniformCoordinatesExplicit(DM dm, PetscReal xmin, PetscReal xmax, PetscReal ymin, PetscReal ymax, PetscReal zmin, PetscReal zmax)
Collective
Input Parameters#
dm - the
DMSTAG
objectxmin - minimum global coordinate value in the x direction
xmax - maximum global coordinate values 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#
DMSTAG
supports 2 different types of coordinate DM
: either another DMSTAG
, or a DMPRODUCT
.
If the grid is orthogonal, using DMPRODUCT
should be more efficient.
Arguments corresponding to higher dimensions are ignored for 1D and 2D grids.
See the manual page for DMStagSetUniformCoordinates()
for information on how
coordinates for dummy cells outside the physical domain boundary are populated.
