# DMDALocalInfo

C struct that contains information about a structured grid and a processors 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;

Developer note: Then entries in this struct are int instead of PetscInt so that the elements may be extracted in Fortran as if from an integer array
