请教版主GroupToGroupReport问题

blaiman

版主好我用一个简单的模型，建立GroupToGroupReport在结束的时候，运行目录里面就有一个GroupReport.xls和一个GroupReport.dat；但是一个大模型就不行了，虽然也有GroupReport.xls，可是没有GroupReport.dat。是不是模型复杂的时候GroupToGroupReport不够用了啊？

TMG creates a file GroupReport.xls (GroupReport.dat on UNIX)

呵呵,具体的大模型我也没有试过..

blaiman

后来我修改了还是不行，比较郁闷，还在不断修改尝试中

yueyaba

帮助文件说是在UNIX系统上生成GroupReport.dat ....你用的是什么系统?

blaiman

windows xp sp2但是有个小模型是可以生成的，还有个unit.txt文件，它们一起被GroupReport.xls调用，就实现了excel中查看组对组的热流、辐射等等信息

blaiman

不管是稳态还是瞬态的都没有生成正确的文件，郁闷中

我以前也遇到过这种情况，也是大模型，具体怎么处理的忘了。不过给你几个建议：
把组报告都删了，重新建一遍；
把模型输出来，然后重新导入，再看一遍；
呵呵，如果不介意可以把模型发给我看看！

engima

再挖老帖:dizzy:
我目前也遇到了这个问题：在打开groupreport.xls时被告知没有groupreport.dat；也出现过被告知没有units.txt文件而无法打开。
请问这到底如何解决啊（我的系统也是xp的）咋还没朋友帮忙解答啊
