摘要
针对组合网格法在求解特殊类型的工程问题时求得数值解精度低的缺陷,提出一个改进计算格式的组合网格法.粗细两套网格都是在各自区域上单独剖分,两套网格互不影响,在粗网格上达到粗网格的精度,在细网格上达到细网格的精度.该方法的网格剖分为粗网格和细网格,能够大大提高数值解的精确度.
In solving special projection ,combination grid method produces low precision numerical solution. This paper puts formard a new combination grid method which can improve computation form. This method has two sets of grids in the whole area, coarse grid, and fine grid. They are analyzed alone in the respective region, and do not affect each other. Numerical solution reaches its precision on coarse grid and its precision on fine grid. This method can improve numerical solution precision.
