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！

数据文件上传不了，只能复制下来了

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，

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。
