Develops the two dimensional mathematical models for direct-buried pipes and in-duct pipes and solves them using the boundary discretization method.
建立了供热管网直埋、地沟敷设管道的二维数学模型，通过边界离散方法进行了求解。
By introducing the concept of "nihility point" and the method of "spherule bounding" in the algorithm, we have simply and effectively realized boundary discretization in 3-d space.
这种算法采用“虚点”概念，按照一定的规则用“小球跳跃法”简单而有效地实现了三维场域边界的三角形离散。
The finite volume discretization method and treatment of boundary condition were presented.
采用有限容积法离散方程，附加源项法处理边界条件。
The quadratic isoparametric interpolation is adopted in discretization. An approximate averaging method is proposed to smooth out the boundary stresses and more accurate results are thereby obtained.
