BAO22如何设置参数

各位大侠,请教个问题啊,BAO22这个子模型的后两项参数怎么设置啊,倒数第二项 expression or file area=f(underlap)的意思是不是要指定通流面积与阀口开度的关系式啊,或者指定一个二维数据文件?可是我指定一个文件后运行发现变量里同流面积为0啊,是不是指定的文件有问题,请大侠帮我看看啊。还有最后一项dh是啥意思?是不是倒数第二项指定了文件后,这一项就可以不设了?在这先谢各位了!{:10_215:}

指定的文件换成txt格式 试试?

我是这样的,加载了一个TXT文档,做个一个表,比如x y:x代表位移,单位m;y代表过流面积,单位m^2,都是运行是时候出现加载失效,不知道怎么回事

.dat格式,然后加载进去就行了,这只是个二维表x表示自变量y表示因变量,帮助里也有这部分的,

xuexiyeya 发表于 2013-8-24 09:07:13

是你单位的问题,表格的默认单位是m,m^2,你看你的数据 明显是mm级的单位。正常情况下阀芯的位移哪有论米的? 把m换算成mm就好了。
