Referring to objects of internal flowsheets

[Dmitry]

Hello, Daniel!

My flowsheet includes subflowsheet "FS-03" as an element as shown in the screenshot.
I am trying to get the subflowsheet item as you pointed out in the topic:
https://sourceforge.net/p/dwsim/discussion/scripting/thread/69416729/

clr.System.IO.Directory.SetCurrentDirectory(DWSIM_PATH)
clr.AddReference('Interfaces.dll')
clr.AddReference('Automation.dll')

process = Automation.Automation()
process = process.LoadFlowsheet(PATH_TO_FLOWSHEET)
flowsheet = Interfaces.IFlowsheet(process)
sim = Automation.Automation()

fs_object = flowsheet.GetFlowsheetSimulationObject('FS-03')
subfs_object = fs_object.Fsheet
mstr_object = subfs_object.GetFlowsheetSimulationObject('gMSTR')
mstr_temperature = mstr_object.GetPropertyValue('PROP_MS_0', None)

But the method GetFlowsheetSimulationObject('FS-03') or GetObject('FS-03') returns None, and fs_object in my case does not contain an attribute Fsheet.

Also, code

for objects in flowsheet.SimulationObjects:
    print(objects)

returns a list that does not contain an object "FS-O3"

1) How can I refer correctly to the subflowsheet, inside the main flowsheet?
2) I also got stuck on the question: how to get the final value of the spreadsheet cell, which was calculated using the formula inside the spreadsheet?
Are there any tips or examples?

Thank you!

Replace this

process = Automation.Automation()
process = process.LoadFlowsheet(PATH_TO_FLOWSHEET)
flowsheet = Interfaces.IFlowsheet(process)
sim = Automation.Automation()

by this

aut = Automation.Automation()
flowsheet = aut.LoadFlowsheet(PATH_TO_FLOWSHEET)

Thank you, Daniel!

As far as I understand, the rest of the code is correct and in this way i can refer to the elements of the subflowsheet?

I don't see anything wrong, it should work...

Notice that the object id is FS-03 with a zero, not with an "O".
