PetscErrorCode DMStagSetUniformCoordinates(DM dm, PetscReal xmin, PetscReal xmax, PetscReal ymin, PetscReal ymax, PetscReal zmin, PetscReal zmax)
Collective
Input Parameters#
dm - the
DMSTAGobjectxmin - 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: DMSTAG and DMPRODUCT.
Arguments corresponding to higher dimensions are ignored for 1D and 2D grids.
Local coordinates are populated (using DMSetCoordinatesLocal()), linearly
extrapolated to ghost cells, including those outside the physical domain.
This is also done in case of periodic boundaries, meaning that the same
global point may have different coordinates in different local representations,
which are equivalent assuming a periodicity implied by the arguments to this function,
i.e. two points are equivalent if their difference is a multiple of \((\)xmax \(-\) xmin \()\)
in the x direction, \((\) ymax \(-\) ymin \()\) in the y direction, and \((\) zmax \(-\) zmin \()\) in the z direction.
