摘要： 在子域精细积分法的基础上,提出解偏微分方程的变网格差分精细积分法,这种方法既具备子域精细积分法的各种优点,还能较好描述非均匀介质的物理特性及灵活处理各类边界条件,且其显式计算格式是无条件稳定的
关键词: 偏微分方程, 差分法, 数值稳定性
Abstract: The arbitrary difference precise integration method (ADPIM) is advanced to solve PDEs,from improving the subdomain precise integration method.The new one contains all the merits that the older one contains,and can also describe the physical properties of inhomogeneous media and convenient treatment of various boundary conditions,while the explicit integration Schemes given by ADPIM are proved unconditionally stable.
Key words: ADPIM, difference method, numerical stability
