闪蒸模拟过程出现错误
本帖最后由 372366169 于 2013-6-28 17:37 编辑闪蒸塔模拟之后出现这个
**ERROR
BLOCK SZ IS NOT IN MASS BALANCE:
MASS INLET FLOW = 0.11604615E+03, MASS OUTLET FLOW = 0.11516358E+03
RELATIVE DIFFERENCE = 0.76636066E-02
MAY BE DUE TO A TEAR STREAM OR A STREAM FLOW MAY HAVE
BEEN CHANGED BY A FORTRAN, TRANSFER, OR BALANCE BLOCK
AFTER THE BLOCK HAD BEEN EXECUTED.
应该如何处理
质量不守恒,建议上传bkp文件看看。 你应该把你的具体要求贴出来吧(具体的流程过程),大哥..... 流程太复杂了 看不懂
就算你这个模型建立设置没有错 但是牵涉到循环比较多 收敛计算顺序不当的话也会出问题的
建议分布模拟最后整合 调整了一下,3号流股不循环的waring和error基本排除掉了。

用的7.3 打不开现在正在下8.0呢 {:1106_364:} 好好学习,天天向上 好好学习,天天向上,看看!

路过回复看看 tianshanxue 发表于 2014-1-17 00:43
路过回复看看
我记错了 我这还是通的是原料
但是现在还是出错了 希望给解决一下 372366169 发表于 2013-6-30 08:57

我用的是7.3.2 版本的aspen plus tdl522 发表于 2013-6-29 10:45
调整了一下,3号流股不循环的waring和error基本排除掉了。

大哥 用的是8.0版本的把 正在安装当中 下完之后好好学习一下 飘逸的枫324 发表于 2013-6-28 19:23
你应该把你的具体要求贴出来吧(具体的流程过程),大哥.....
就是合成氨的时候 布朗工艺深冷净化系统的模拟过程说我怕说不明白 您可以上
网去看一下文献 过程是比较简单的一个但是模拟起来真的好难 飘逸的枫324 发表于 2013-6-28 19:23

请问一下 您是如何修改的呢 这个是因为物料循环太多次所以出现了错误吗? 下载下来看看 看看,最近循环卡死了都
