The multigrid techniques are added to accelerate the convergence of flow and adjoint equations to improve the efficiency of design.

为了提高计算效率，将多重网格方法应用到方程的数值求解中来加速收敛。

Flow convergence region, which was located in the left ventricular sides of mitral valve, was displayed in 63%(33/52)of physiological MR and 100%(87/87) of pathological MR.

结果发现：33／52（63％）例生理性二尖瓣返流和87／87（100％）例病理性二尖瓣返流可于二尖瓣左室面显示血流会聚区；

Meanwhile, this paper also simplified the iteration flow of transient stability computation and improved the scheme of convergence checking.

同时，文中还简化了暂态稳定算法迭代流程，改进了全局收敛判定方法，有效地减少了算法计算量和通信损耗。
