PetscErrorCode DMGetCoordinatesLocal(DM dm, Vec *c)

Collective on dm

Input Parameter

dm

- the DM

Output Parameter

c

- coordinate vector

Note

This is a borrowed reference, so the user should NOT destroy this vector

Each process has the local and ghost coordinates

For DMDA, in two and three dimensions coordinates are interlaced (x_0,y_0,x_1,y_1,...) and (x_0,y_0,z_0,x_1,y_1,z_1...)
