提出了具有非均匀网格间隔 hi 的有限差分网络,使得 hi = hi-1 + O ( h 2 i-1 ) 。使用网格网络对线性边界层问题的 h i - h i-1 的两个特定选择表明,它在计算效率和解析解表示的准确性方面具有明显的优势。 DOI:10.1111/j.2153-3490.1970.tb01933.x
A finite difference network with non-uniform grid intervals, h i , such that h i = h i-1 + O ( h 2 i-1 ) is presented. The use of the grid network for two specific choices of h i - h i-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.
