Hello,

I'm doing a transient analysis of tank exhaust, the model is very simple, just a tank with a open. I need to know how much mass of air flow out from the open at every time step rather than calculating them after all steps.

Could somebody tell me how to use CCL or Junction Box Routine to sum/accumulate the flow mass at each step?

Thanks very much!

Hi,

Setup a monitor point defined to be the massFlow()@Outlet or similar. For the total stuff left in the tank use a monitor point defined as mass()@Tank.

You can then view these values as a function of time as the simulation progresses in the Solver Manager.

...i.e. you don't need a Junction Box routine.
