摘要
对于具有多种透水介质的堤防地基用波前法进行有限元网格自动剖分,通过背景网格密度函数的办法控制网格的尺寸,并在网格有效性的检查上对波前法进行改进。研制的网格生成计算机动态显示界面具有数学计算、人机对话、图形显示及修改等功能,不但使得网格自动生成的前处理工作可以在可视化平台上直接进行,而且可以在该平台上修改已有的有限元网格,显示与检查不同介质区域边界信息,生成边界条件数据等。
Two dimensional unstructured triangular mesh is generated based on the wave front method. By checking the sides of the new element with the active front, the present work has good computational efficiency. Graphical Utility (GUI) is developed, which can display the grid, the boundary information dynamically, the grid modification and the boundary conditions. The contribution of present investigation is to combine the wave front algorithm with the GUI technique, which make the mesh generation easier.
