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
本帖最后由 长夜未央 于 2011-5-11 15:26 编辑正在用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：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 账户问题，楼上各位都告诉你了 主要是物性方面的问题，高版本aspen无account的问题。 denghuimin 发表于 2011-5-15 10:32
还有计算结果超出范围
WARNING IN PHYSICAL PROPERTY SYSTEM
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

这又是什么问题 denghuimin 发表于 2011-5-15 10:32
还有计算结果超出范围
并不是账户问题啊 zyx-iccas 发表于 2013-3-26 18:46 static/image/common/back.gif
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 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 还有计算结果超出范围 生物柴油这玩意不懂{:1106_365:} 生物柴油组分你是怎么定义的？
