# DALocalInfo

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 pointd 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 */
      DAPeriodicType pt;
      DAStencilType  st;
      DA             da;
    } DALocalInfo;

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
