Mesh mapping techniques in metallurgical engineering

1.对于面来说，使用映射网格划分需要满足以下几个几何拓扑结构的要求条件：

geometrical topology conditions: For surface, using a mapping grid needs to meet the requirements of the following

*面必须有三条或四边线的边界组成

*The boundary of the surface must have three or four line

*一般来说，对边的应划分成相等的个数

*In general, the edge should be divided into equal number

映射网格划分一直是大家关心的问题，现把自己使用ansys的一些经验及编程的真实体会奉献给大家，希望能达到授之以渔的效果。

Mesh mapping has been a problem, everybody CARES now to some real programming experience and experience of using ansys give you, hope to be able to achieve the result of teach to fish.

ansys执行映射网格划分的条件是：对于面，必须是三角形或四边形，对于体，必须是四面体、五面体或六面体，这是众所周知的，但往往忽略了另一个条件：划分数的匹配问题，对于四边形而言必须满足对边划分数相等的条件，对于三角形，在后面作专门介绍。其实ansys不仅可以对三角形和四边形执行映射网格划分，对任意多边形原则上（划分数匹配）都可以执行影射网格划分，这些

quadrilateral, for the body, must be a tetrahedron, pentahedron or hexahedron, it is well known, but often overlooked another condition: dividing the number of matching problem, must satisfy the edge for quadrilateral partition number equal conditions, for triangle, introduce specifically in the rear. Actually ansys can not only the triangle and quadrilateral mesh mapping, execution of arbitrary polygons in principle (partition number matching) can perform mapping grid, these methods include: the cutting, wire, etc, these methods can also be used in the mapping of the mesh.

我今天要介绍的是另一种方法（可能在论坛上已经有类似的介绍，但我还没有看到，如果有，就算重温吧）也即amap命令（基于面的角点的映射网格划分）的使用，它需要指定要划分的面的编号，以及以任意顺序指定该面上的任意4个角点（注意：任意四个角点是有前提的，即划分数的匹配，为了不再罗嗦，以后不在重复强调这个问题）。
