To assure astringency , some technologies have been used such as iterative penality function methods , assemblage mass matrix , reduced integration algoritlun , newton iteration method with parameters for non - linear equation set , introducing relax factors and double steps solution and so on , and an algorithin for solving the nonlinear equation set of flow field by fem has been presented
基于有限元法建立了流场求解列式，为保证其收敛性，采用了迭代罚函数法，集中质量矩阵，缩减积分计算，带参数的newton迭代求解，引入松驰因子及双层解法等技术，提出了一套适合流场有限元方程计算的非线性方程求解方法。
