A finite difference network with non-uniform grid intervals, hi, such that hi = hi-1 + O(h2i-1) is presented. The use of the grid network for two specific choices of hi - hi-1 for a linear boundary layer problem shows that it has distinct advantages in computational efficiency and in accuracy of representation of the analytical solution.DOI: 10.1111/j.2153-3490.1970.tb01933.x
