PetscErrorCode DMDAGetPreallocationCenterDimension(DM dm, PetscInt *preallocCenterDim)
Input Parameter
Output Parameter
|  | preallocCenterDim | - The dimension of points which connect adjacent entries | 
Notes
    FEM:   Two points p and q are adjacent if q \in closure(star(p)), preallocCenterDim = dim
    FVM:   Two points p and q are adjacent if q \in star(cone(p)),    preallocCenterDim = dim-1
    FVM++: Two points p and q are adjacent if q \in star(closure(p)), preallocCenterDim = 0
