The correct placement of the cycler closer -- Add 'note' in doumentation

[maltefritz]

In a process with splitter and merge, I noticed that the location of the cycler closer is not trivial. The process works only if the component is placed in the part where the total mass flow is present.

So that others are not confronted with the same problem, I suggest to put the following note in dokumentation in 'tespy.components.basics.cycle_closer module':

If a cycle process is separated by a splitter or similar and reconnected by a merge or similar, this component has to be placed in the part of the prozess where the total mass flow is present.

If I find time, I will create a pull request to add this to the documentation.

Best regards

Hi @maltefritz,

thanks for reporting, do you have a minimal working example for that? I guess something like

a -> b
b -> c
b -> d
c -> cc (cycle closer)
cc -> e
d -> e
e -> a

does not work then, while placing the cycle closer between e and a or a and b would work?

Hi @fwitte,

your working example is right. The cycle closer only works between a and e or a and b. I think this component has to be placed in the part of the process where the total mass flow is present.
