I am modeling water supply in my Community. The supply is rashened due to demand outmatches supply.

I need to calibrate such a system and I am faced with challenge, since supply in nt to the entire network at atime but rather to sections.

Please I need help:

1) How to model such supply system ( I intedned to put flow control valves at certain locations and put cammand on when to open and Close but this is becoming a challenge) Kindly update me with proceedure to write the commands, if any or any other approach to achieve my objective.

2) On how to use the Dawin calibrator to work in this case,

Thank you
