Examples
- There are two type meshes , mathematic mesh and physical mesh for the general definition of manifold
在流形一般化定义下，流形方法具有两种独立的网格? ?数学网格和物理网格。 - Mathematic mesh is composed of folded covers and could be random set by final user , and physical mesh is composed of real material boundary , joints or discontinuities , phase interfaces etc and could n ' t be artifical
数学网格由折叠的覆盖组成，物理网格则由实际的材料边界、裂缝、块体、不同材料的交接面甚至不同的材料相的界面等组成。 - The integral area ' s shape can be arbitrary , its shape is the intersecting part of physical grid and mathematics grid , so , the generation of integral area of unit is an intersection operation of two polygons
摘要由数学覆盖和物理网格形成的流形单元的积分区域可以有任意形状，其形状为物理网格和数学网格的相交部分，所以流形单元积分区域的形成为两个多边形（数学网格和物理网格）的求交运算。 - Compared with the traditional numerical method , the numerical manifold method need not calculate the released load on excavation face , need not prepare special element for unloaded material part ; simple mathematic grid can meet the arbitrary course of excavation ; so it is more convenient and effective ; at the same time , high - order manifold method has better precision for excavation
相对于传统数值方法，数值流形方法在模拟开挖时不用计算开挖面上的释放荷载，不用为卸除的材料部分准备专门的单元，简单的数学网格可以适应任意的开挖过程，使其对开挖的模拟更加简便和有效，同时高阶的流形方法对开挖问题具有较高的求解精度。
