DMDALocalInfo#
C struct that contains information about a structured grid and a processes logical location in it.
Synopsis#
typedef struct {
PetscInt dim, dof, sw;
PetscInt mx, my, mz; /* global number of grid points in each direction */
PetscInt xs, ys, zs; /* starting point of this processor, excluding ghosts */
PetscInt xm, ym, zm; /* number of grid points on this processor, excluding ghosts */
PetscInt gxs, gys, gzs; /* starting point of this processor including ghosts */
PetscInt gxm, gym, gzm; /* number of grid points on this processor including ghosts */
DMBoundaryType bx, by, bz; /* type of ghost nodes at boundary */
DMDAStencilType st;
DM da;
} DMDALocalInfo;
Fortran Note#
This should be declared as
`DMDALocalInfo` :: info(DMDA_LOCAL_INFO_SIZE)
and the entries accessed via
info(DMDA_LOCAL_INFO_DIM)
info(DMDA_LOCAL_INFO_DOF) etc.
The entries bx,by,bz, st, and da are not accessible from Fortran.
