Loop a Dynamic Simulation

[Jiajun Duan]

Hi Daniel,

I have created a dyamic model as shown below.
Now, I want to write a loop to set different PI gains to see the effects.
I have set
schedule = Flowsheet.DynamicsManager.ScheduleList[Flowsheet.DynamicsManager.CurrentSchedule] integrator = Flowsheet.DynamicsManager.IntegratorList[schedule.CurrentIntegrator]
Do you know how which command I should use to run the dynamic model instead of clicking "Run Schedule" button on Inegrtor Controller? Also do you know how to adjust the PI gains?

Thanks,
Jiajun

Hi Jiajun,

I still have to implement an API for that. I apologize.

Hi Daniel,

May I ask if the API is ready for use now?

There is a sample called" Heat Exchanger" in DWSIM, and I'm trying to run the dynamic model.

Another question is, I'm going to set the events with python, but the EventSetList which i read from the flowsheet is a interface:
manager = Automation3()
filepath = "D:\Windows\Heat-Exchanger.dwxmz"
myflowsheet = manager.LoadFlowsheet(filepath)
dymanager = myflowsheet.DynamicsManager
for key, value in dymanager.EventSetList.items():
event_set = value#<class 'dwsim.interfaces.idynamicseventset'="">
for key, value in event_set.Events.items():
event_list.append(value)#<class 'dwsim.interfaces.idynamicsevent'=""></class></class>
How can I get the object from the .dwxmz and set the events by myself?

Thank you so much!
Sincerely,
Wei
