正在用Aspen做生物柴油的模拟。做完之后现在就剩下一个错误了。错误提示信息是：错误.png

请高手指点一下，问题处在了哪里。我看别的都给错误的地方。这个怎么都没给错误的地方呢
刚才在别人的机器上模拟了一下。出现的提示是：

求高手指点一下。谢谢啦~

应该是一楼的指出的问题，11.1版本的必须在设定全局信息时设定account，随便写就行。

你是做哪一部分的模拟?单元很多,不是随便一个单元就可以完成

用户信息没有填写

imeagor · 发表于 2011-5-11 15:20:52

账户问题，楼上各位都告诉你了

zyx-iccas · 发表于 2011-5-11 15:20:52

主要是物性方面的问题，高版本aspen无account的问题。

还有计算结果超出范围

   PARAMETER PLXANT (DATA SET 1) FOR COMPONENT NAOH:
   UNREASONABLE VAPOR PRESSURE CALCULATED AT NORMAL BOILING POINT.
   VALUE SHOULD BE WITHIN 10% OF 1D5 N/SQM.  PLEASE CHECK YOUR INPUT
   FOR THE ANTOINE PARAMETERS.

****PROPERTY PARAMETER ERROR
   ERRORS ENCOUNTERED IN CALCULATION OF IDEAL GAS PROPS FOR

   PLEASE FIX THE ERRORS, RE-INITIALIZE, AND RUN AGAIN.

! Calculations stopped because of missing  property parameters

这又是什么问题

并不是账户问题啊

登录/注册后可看大图

主要是物性方面的问题，高版本aspen无account的问题。

咱俩回复相差好久额…

谢谢了，学到了

也就是有的物性参数没有无法计算

楼主辛苦了

denghuimin · 发表于 2011-5-15 10:27:31

setup里的account信息没填写。你是11.1版本的吧？06版以后的就不会出这个问题

生物柴油这玩意不懂{:1106_365:}

斜月三星 · 发表于 2012-3-23 21:34:26

生物柴油组分你是怎么定义的？

做生物柴油的模拟。模拟完好不容易就剩下一个错误了。但是找不到哪里的错误。麻烦高手
