标题: 求助分析提示 [打印本页] 作者: goodxxw 时间: 2004-12-17 22:53 标题: 求助分析提示 我刚开始用MPI,分析时出现了以下提示不知何义,请各位大哥指点.
1. the mesh many have problems, the match ratil is 84%,and the raeiproal match ratil is 74%.
2.the thickness of element 3925 has the wrong order of magnitude check the geometry or mesh date .作者: zg0609 时间: 2004-12-18 12:09
第一个说的是网格匹配问题，按要求流动分析达到85%以上，翘曲分析达到90%以上，不过，对于复杂的结构很难达到这个要求，不去理会它，问题也不大。
第二个说的是3925单元的厚度有问题，可以查询一下网格的厚度，重新设置一下就可以啦。作者: goodxxw 时间: 2004-12-18 19:11

再次麻烦指点一下
1.element 328 has a very had shape
2. warnin 702352 elements 8 and 1258 are orerlapping or too close ,the analysis may not be able to resolve these problem elements during analysis .it is recommended that you improve the in this region of these elements.
3.warning the mesh many have problems the match ratil is 80%,reciprocal match ratio is 69%.
4.warning teh average aspect ratil is >5.0 for triangle elements ,the recommended average aspect ratio for elements is ~5.0
5.warning the mesh size is not appropriate for this part.作者: Suni Lee 时间: 2004-12-20 09:19
1、328单元纵横比太高
2、单元8和1258的几何中心靠的太近或两个单元发生了重叠。
3、同上
4、平均纵横比大于了5，要求单个单元纵横比小于6。平均纵横比小于5
5、网格单元过于粗糙，需要重新细划网格作者: goodxxw 时间: 2004-12-23 15:56
thank 老大
我还想问一下网格匹配率太低,怎么解决
