I am using a stochastic element to simulate inflows and i would like to create a vector with monthly totals.  I have been successful so far with setting up my integrator element to calculate the correct monthly sum and reset the integrator at the start of the month.  However, when i try to populate the vector, the value is not sent correctly. 

I am using a discrete change element (populate_vector) using the equation: vector( if(row= Month_Counter, Monthly_Integrator, 0 m3))

Followed by a monthly_sum integrator element with the discrete change set to the above element.   When i check this results of this element, the values are not correct.   

Does anyone have any suggestions?  Thank you

  This is the wrong way to approach this.  Instead, you should use Reportion Periods (https://help.goldsim.com/#!Modules/5/definingreportingperiods.htm)

  i want to use the monthly sums and also use  monthly explosive usage to predict ammonia concentrations so i need them in the simulation.

  Ashley,

  How about something like this: Monthly and Annual Totals – GoldSim Help Center
