某板的模态分析中采用shell63单元
当采用四边形单元,自由网格划分方法时给出以下警告:
*** WARNING *** CP = 6.953 TIME= 17:50:11
Shape testing revealed that 23 of the 2857 new or modified elements
violate shape warning limits. To review test results, please see the
output file or issue the CHECK command.
outpt window 里面显示:
parallel deviation 有十个警告;maximum angle 有十三个警告
向高手请教两个问题:
1、parallel deviation是什么意思
2、如何处理上面的警告信息
当采用三角形单元,自由网格划分方式时给出以下警告:
*** WARNING *** CP = 2.547 TIME= 18:58:23
Structural elements without mid nodes usually produce much more
accurate results in quad or brick shape.
请问这是什么意思,如何处理?
