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.
