做了一个立方体,对其中的nodes分析,明明选中为什么下面分析却说没有定义nodes.
不知道是为什么啊!!立方体如下面。然后执行Utility manu->select->entities.出现select entities对话框。
然后分别选择nodes, attached toareas,all,最后选择from full,之后点击OK。
在下面计算一个热力学里面对流中的convection->on nodes之时,提示:
This function requires defined nodes.No nodes are currently defined.
命令行中对上面操作的提示是:
ALL NODES(INTERIOR TO AREA,INIERIOR TO LINES,AND AT KEYPOINTS)RELATED TO SELECTED AREA SET.
0 NODES(OF 0 DEFINED)SELECT FROM
13 SELECTED AREAS BY NSLA COMMAND.
请问怎么解决啊? 划分网格否 ?
