Regarding Aspen nested loops
Thread Content
I would like to ask all the teachers and fellow users a question: when there are two convergence modules, $OLVER01 and $OLVER02, in nested loops within the control panel of the Aspen process simulation, how can one modify the tolerance for the flow rate in the inner loop? ? ? Thank you so much! ! !
Have you tried manually setting the logistics of your internal loop as Tear logistics or a tearing flow, and then specifying the convergence accuracy for this tearing flow in Convergence | Tear?
I’ve tried it, it doesn’t work! Thank you.
Create new convergence
Thank you very much, teacher, for your reply. Teacher, when performing a complex process simulation, is it generally advisable to use the calculation sequence provided by Aspen, or should one define their own sequence? Thank you, teacher.
First of all, one must trust the software, as it usually provides a good order for calculations; if one wants to specify something themselves, they need to have a thorough understanding of the process and calculations. It is generally rare to use a sequence specified by oneself.
