请问如何才能用mapped划分网格?
本帖最后由 bacrang 于 2011-3-23 17:17 编辑比如要得到下图中的网格划分,必须要把这个Area分割成两个梯形吗?否则提示说形状不规则不能用 mapped 划分。。
还有ansys help里面Free or Mapped Mesh中的例子,
右图中的mapped mesh网格要怎样得到?难道都必须划成四边形后才可以?
必须是三角形或者四边形,具体参考帮助:
For an area to accept a mapped mesh, the following conditions must be satisfied:
1、The area must be bounded by either three or four lines (with or without concatenation).
2、The area must have equal numbers of element divisions specified on opposite sides, or have divisions matching one of the transition mesh patterns.
3、If the area is bounded by three lines, the number of element divisions must be even and equal on all sides.
4、The meshing key must be set to mapped . This setting results in a mapped mesh of either all quadrilateral elements or all triangle elements, depending on the current element type and/or the setting of the element shape key .
5、If your goal is a mapped triangle mesh, you can also specify the pattern ANSYS uses to create the mesh of triangular elements . If you do not specify a pattern, ANSYS chooses one for you. See the MSHPATTERN command description in the ANSYS Commands Reference for an illustration of the available patterns.

谢谢!原来帮助里有哇
刚刚看到帮助里有个 MultiZone Meshing 貌似可以用,学习下先 bacrang 发表于 2011-3-24 09:56 static/image/common/back.gif

MultiZone技术是Workbench中的功能 回复 4 # Chelsea 的帖子
难怪没有找到怎么设置。谢大神!
可是很多地方不能用mapped mesh 这样很麻烦呢。 bacrang 发表于 2011-3-25 15:22 static/image/common/back.gif

这是没办法的,做有限元分析,如果结构复杂点一般80%以上的时间和精力都是花在网格划分上的 可以先用LCCAT命令把一些边线连起来了再分网格吧!~1
