Hi,

I would like to know if anyone has implemented a pressure driven water distribution model with multiple emitter exponents (Epanet has a coefficient emitter for each node but it is possible to use only an emitter exponent). I wrote the equations system in matlab with a different emitter exponent for each node but , the system is often unbalanced and a solution is not found.(not always, probably depending on the values I give to the exponents).

Can you help me?
