Define Simulation Time - Volume flow rate BC

Hello to all

I'm working a model of a curved weir where i need to enter a Volume Flow Rate Boundary Condition at Ymax. The problem is that my Volume Flow Rate hydrograph has a duration of 72h=104400sec. How can i manage to run this simulation. Is it right to set a Finish time of 104400sec in the Finish time window in Global tab?.I see that the default value of software is 100 sec in which my flow hydrograph hasn't even reached it's peak.

So what can i do about it?

Thanks in advance
