DMStagGetProductCoordinateLocationSlot
get slot for use with local product coordinate arrays
Synopsis
PETSC_EXTERN PetscErrorCode DMStagGetProductCoordinateLocationSlot(DM dm,DMStagStencilLocation loc,PetscInt *slot)
Not Collective
High-level helper function to get slot indices for 1D coordinate DMs,
for use with DMStagGetProductCoordinateArrays() and related functions.
Input Parameters
| dm | - the DMStag object
|
| loc | - the grid location
|
Output Parameter
| slot | - the index to use in local arrays
|
Notes
Checks that the coordinates are actually set up so that using the
slots from the first 1d coordinate sub-DM is valid for all the 1D coordinate sub-DMs.
