哥哥们,最近小弟碰到个节点的网格划分问题。希望各位邻居们给点参考意见。详细见下图:
接触是这样的,四个小圆和大圆上面都还有一个方形块的底面与其绑定(tie),方形块的单元是C3D8R,上图结构的单元是C3D10H,
但是在提交作业之后,出现的warnning就是The volume of 35 elements is zero, small, or negative. Check coordinates or node numbering, or modify the mesh seed. In the case of a tetrahedron this error may indicate that all nodes are located very nearly in a plane. The elements have been identified in element set ErrElemVolSmallNegZero.
然后就直接被Aborted了,出现了上图的错误。各位哥哥们,这个该怎么解决啊,查了好多资料,节点顺序,接触面啥的,但是真的没法解决了。重新画网格之后还是出现这样的问题,大神们,这该怎么办啊,有什么好的办法避免上面的错误的
