| Abstract: | It is impossible to know the boundary of 2-D flow field with free water surface previously. In order to suit this condition better, the theory of function Y is applied to derive finite element equation for steady flow of incompressible ideal fluid in mapping plane. And the example of finite clement computation of weir flow is given in this paper. |
