怎么是文本文件，看不懂。

djh713 发表于 2006-10-20 13:38

simwe上的原例子，有没有SYSNOISE的，最好有与实验验证的

kk20201 发表于 2006-10-31 18:33

什么东西呀，怎么看不懂呀

blb_ustb 发表于 2007-3-2 15:26

看不懂！

榫眼 发表于 2007-3-15 15:02

不明白!

jzx11082 发表于 2007-3-22 13:01

是程序吗？？？

pengweicai 发表于 2007-3-22 13:43

ansys的命令流文件。

米兰之光 发表于 2007-5-10 20:26

大概是一篇论文的命令流《ANSYS在抗性消声器分析中的应用》。没重做过，不确定。

zhchyl999 发表于 2010-1-14 21:39

楼主能具体解释下后处理的命令吗，我也是做了个三维的，可是吧后面的命令粘贴过去，图形变红了，没有显示等值线呀，

yefangbiao 发表于 2011-5-6 16:01

终于看懂了

yefangbiao 发表于 2011-5-7 16:37

好东西啊！
