Hello everyone,
I´m using Hammer Bentley v8i and I can´t get the discharge pressure on the system, I´m trying to simulate a positive displacement pump, and I should have a discharge pressure of 1100 psi and the program estimated 869 psi, instead. What kind of variable can I modify to adjust the discharge pressure according to the required value?
Best Regards,

Thanks MPachlhofer and Jesse for your answers,
Jesse I’m sending my model, I’ll explain you the main data:
I used other simulator (Pipephase) to evaluate the data provided from final user where I considered the viscosity between 3494 @122°F and 791.9 @100°F, and I got the pressure on the network approximately (The initial and final pressure is 1538 psig and 18 psig respectly). I assumed average viscosity (1482.8 cS), this was used in Hammer but I'm not sure if this is correct. The operation temperature is 100 °F.
First the fluid starts it's route through a screw pump (I want to simulate through “Periodic Head-Flow”) to a storage tank, also on the network I have two check valves in pipes P-127 and P-224 as you can see on the model. When I run the system it gets the error, and I remove the check valves and the system runs correctly. I have tried with Check Valve tool and the result is the same.
