aspen v7的运行错误? 我做的是一个间歇反应精馏,计算时出现了一下错误是什么原因?怎么解决啊? 感谢大侠们帮忙 ->Processing input specifications ... Flowsheet Analysis : COMPUTATION ORDER FOR THE FLOWSHEET: B1 ->Calculations begin ...

Solution returned to the best point at parameter value 0. Attempted initialization step at 0 failed Problem failed to converge HomFrac=0 Initialization at total reflux using homotopy failed to converge. Some possible reasons for failure are: Specified initial charge may be smaller than the sum of the holdups specified for the stages and drum. Specified or calculated pot duty may be too small. Non-condensibles may be present in the initial charge.
