Hi Goldsim community, 
The tank should be empty when inflow = outflow. But the diagram shows a variation of the volume in the pool element. Although it is very tiny, but keen to know the reason. Any advice would be a great help.  Many thanks.

  Impossible to really understand your problem just based on a figure and without seeing your model, but I'm guessing that this is due to a numerical rounding error related to how are the inflows and requests being specified (perhaps one is specified directly and one is calculated). Note also that although GoldSim carries out its calculations in double-precision, the saved results are in single precision.

  Hi Rick, 

  Thanks for your response. Do you think allowing unscheduled updates will cause this issue?. 

  Many Thanks
