DMStagSetUniformCoordinatesExplicit#

set DMSTAG coordinates to be a uniform grid, storing all values

Synopsis#

Collective

Input Parameters#

  • dm - the DMSTAG object

  • xmin - 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.
