In addition, experiment had proved under the premise of promising precision, bigger mesh spacing could be used to improve calculative efficiency.
另外，实验验证了在保证一定精度的前提下，采用较大的空间网格间距，可以提高计算效率。
For this end a mesh with a 5ox5o spacing was used.
为此目的采用了格距为5ox5o的网格。
By introducing regional node spacing function, which given a numerical value or varied grade of cell, the mesh could control the changes of element size.
该方法通过引入区域内节点间距函数，人为给定某一定值或渐变数值可在任一局部水域进行网格加密。
