对对流占优的三维溶质运移问题提出了分步广义迎风解法，首先利用Ｎ．Ｎ．Ｙａ－ｎｅｎｋｏ对水动力弥散方程分步求解的思想，将原来的一个定解问题分解为两个定解问题即对流定解问题和扩散定解问题，对对流定解问题采用广义迎风对偶单元均衡法求解，对扩散定解问题采用一般的Ｇａｌｅｒｋｉｎ有限元法求解，不仅避免了用一般有限元法和有限差分法求解对流占优的地下水水质数学模型时常出现数值弥散和过量问题，而且避免了求节点速度这一步，节省运算步骤，对井点的浓度变化给出了更合适的求解方法。
Proposed a step-by-step generalized windward solution to convection-dominated three-dimensional solute transport, using N as a starting point. N. Ya-nenko The idea of a step-by-step solution to a hydrodynamic dispersion equation is to decompose one original fixed solution problem into two fixed solution problems, ie, convection definite solution and diffusion fixed solution. The convection problem is solved by a generalized upwind duality unit equilibrium The general Galerkin finite element method is used to solve the solution to the problem of diffusion, which not only avoids numerical dispersion and over-flow problems in solving mathematical models of convective dominant groundwater using the general finite element method and finite difference method, Nodal speed This step saves computational steps and gives a more suitable solution to changes in the well point concentration.
