A problem when "Zone" is used with "Fluid" library

Hi,

I have a problem when zone is utilized with fluid tools. Let me explain the case first. There are two tanks "FluidTank1-2" that can send their liquid products to one of two lines "FluidToItem1-2" via one of two valves "FluidProcessor1-2". The lines are selected based on a label "Port". I added a "Zone" to make orders to be processed based on "Priority". Once I did that, FluidTank2 is keep sending liquid however, it was not selected by the processFlow. I found that the main reason that the FluidGenerator2 is keep sending to FluidTank2 and the latter is not closing its output port. When I removed the "Zone" from the processFlow, this problem was solved. I am so curious to know why this is happening. I am attaching both case; the one with the zone and the one without.

Best regards,

Hello @Mohamed A17,

Your zone only limits to two tokens (there are no subset or partition constraints), so it will allow tokens in sequential of arrival to the enter zone activity. Your lists will order by priority though.

Hi Jeanette,

Thank you for your reply. I still have a problem that the FluidTank2 is sending a liquid at the beginning of the simulation, however it should be closed at that time. How can I fix that?

Best regards,

Mohamed

If you would like the tanks to have their output closed at the beginning of the simulation then create an on reset trigger that closes their output port
