为什么精馏塔设计规定总是报错操作变量在约束边界上,如图
为什么精馏塔设计规定总是报错操作变量在约束边界上,如图把bkp文件上传上来,已经到下限了。 tdl522 发表于 2013-5-24 14:31
把bkp文件上传上来,已经到下限了。
嗯嗯,谢谢了{:1106_389:}

设计规定没有加载上。

设计规定没有加载上。
怎么解决呢,总是遇到这问题,什么原因

你给我的文件没有设计规定。

你给我的文件没有设计规定。
哦,隐藏了reveral下就可以
就调整到这个纯度了,再往上就难收敛了。另外感觉你的设计规定不太合理。

我是想用回流比还调节塔顶纯度,用塔顶出料调节塔釜中轻组分含量,你认为怎么设计规定
好好看看是怎么解决的。 再次调整,应该达到你的要求了。

嗯,非常感谢,辛苦了{:1106_382:}
@tsl0205 个人能力有限,抛砖引玉,需要各位马友的支持。多多交流。 {:1106_362:}
路过回复看看先 我也遇到同样问题,到底是什么原因,谢谢了 sisteryouyou 发表于 2013-6-9 23:11
