请各位老师看看我的灵敏度分析为啥子不收敛呢。谢谢。

把设计规定隐藏了。

您好，管理员， 您能看我的例子，我非常高兴。由于我的是7.2版本 你的bak文件我无法打开。我试着把设计规定隐藏了。结果是收敛了。但是我仔细看了哈结果。发现有问题。这个题是这样的，经过两次闪蒸使ch4o的摩尔分数提高到50% 如果把设计规定隐藏 就不能保证摩尔浓度是50% 了。我做灵敏度分析的目的是得到 flash1的汽化分率的变化对flash2汽化分率和对产量（stream4）影响。隐藏了设计规定 flash2 汽化分率不变（0.5）.麻烦你在指教。

有点晚了似乎，调整灵敏度分析的范围，同时保证设计规定。

不晚，不晚，谢谢前辈指导。
