aspen dynamics运行显示积分器计算错误
哪位高手帮忙看看:我将aspen稳态文件导入到动态后,初始化顺利通过,但是运行的时候显示如下错误,最后弹出一个提示框:integrator corrector failed……在simulation messages中的信息如下:Step 1: Time = 0.001, step = 0.001 accepted (at min), error/tol = 6.7646
Step 2: Time = 0.002, step = 0.001 accepted (at min), error/tol = 2.3118
Step 3: Time = 0.003, step = 0.001 accepted (at min), error/tol = 1.4171

好像说塔1的冷凝器出了问题,但具体看不懂,稳态里面运行的很好呀,实在解决不了,还请大家帮忙看看,感激不尽!
亲,想请教些关于Aspen动态模拟积分器出现错误的问题,初始化没有问题,一运行就出错误该怎么解决????? 自己顶吗?{:1106_384:} 跟楼主遇到同样的问题,求大侠帮忙解决,感激不尽 我也遇到了 现在还没解决 看来还是自己解决吧 Integrator corrector failed

同样的问题求解,先谢谢各位高手了! 帮顶,遇到同样的问题 请问解决了吗楼主,我也遇到同样的问题,想把入口流量从7000变化到0,出现了同样的错误。是什么原因 请问楼主解决了吗?我的加热器遇到了同样的问题 同求解答,刚接触动态模拟 这个应该怎么修改错误啊?哪位大神指导一下吗? 亲,想请教些关于Aspen动态模拟积分器出现错误的问题,初始化没有问题,一运行就出错误该怎么解决????? 亲,想请教些关于Aspen动态模拟积分器出现错误的问题,初始化没有问题,一运行就出错误该怎么解决????? 月shadow夜 发表于 2016-7-22 15:59

我也是,和你一样的问题,你解决了么?求指点 楼主解决了么,我刚开始做动态模拟,还没有添加控制器,导入后运行就这样的提示,求指教{:1106_382:} 楼主解决了吗 ?同求 也是同样的问题,运行一段时间就出问题 楼主解决了吗 ?同求 - 本文出自马后炮化工论坛,原文地址:https://meng.horse/thread-60843-1-1.html 动态的没有做过。 楼主解决了嘛?想问一下你的初始化的时间是多久,我跑了一天了还在跑,很慌
