The quadrature formula about surface integral on any quadrilateral element is deduced by means of isoparametric transformation and bilinear interpolation.

通過(guò)對(duì)三維有界區(qū)域的邊界曲面作四邊形網(wǎng)格剖分一本热久久sm色国产，用有限元方法處理高斯公式中的曲面積分222aaa男人的天堂免费网址，由等參變換及雙線性插值導(dǎo)出任意四邊形單元上曲面積分的數(shù)值求積公式无码直播毛片久久。

A third order ENO finite volume method for hyperbolic conservation laws on unstructured triangular mesh is introduced.In order to obtain the third order accuracy on spatial discretization,a weighted quadratic interpolation is constructed on every triangular mesh.Two point Gauss quadrature formula is also used on each edge of every triangular mesh and the third order TVD Runge-Kutta method is used for time discretization.The numerical order of convergence and the numerical result of a mesh 3 wind tunnel with one step are given.
