标题:
关于Moldflow建模问题,中心孔问题!!
我建了一个圆柱体,中间有通孔,在moldflow中划分网格时总是出现错误,请各位高手指点应该怎么解决!!
谢谢大家
网格分析出下列结果:
Entity counts--------------------------------
Surface triangles 2784
Tetrahedral elements 0
Nodes 1390
Beams 0
Connectivity regions 1
Edge details---------------------------------
Free edges 0
Manifold edges 4158
Non-manifold edges 9
Orientation details--------------------------
Elements not oriented 34
Intersection details-------------------------
Element intersections 0
Fully overlapping elements 4
Duplicate beams 0
Surface triangle aspect ratio----------------
Minimum aspect ratio 1.167628
Maximum aspect ratio 21.836347
Average aspect ratio 2.643638
继续划分则出现下列错误:
BEGIN: Generating tetras
Generating tetras
TG :-Start tetra mesh generation.
TG :-The maximum allowed aspect ratio as intermediate control is: 25.0
TG :-Transfering Nodes...
TG :-1568
TG :-Transfering Faces
TG :-Number of triangles: 2784
TG :-Building Connectivity
TG :-Triangle with nodes: [N594 N638 N653] not being connected properly.

楼主,你建的是什么圆柱,是用来做什么用的
你给的信息不是很全啊

该圆柱用BEAM单元来构建好了,用三角单元的话质量会很差。
