My branched network consists of near about 3000 junctions(nodes). I used Darwin designer for the above network with pipe dia varying from 15mm to 5000mm, results show that the Pressure at some nodes was as low as -12000MWC and the highest being 340 MWC. When I imposed pressure restrictions it shows Feasibility issues or no valid data as input.
I manually assigned dia to the pipes and results were quite satisfactory (in terms of pressure and velocity, dia being in the range mentioned above). I want to know the reasons for this and what should possibly do for this??

dia optimization.rarHello,
I am attaching it here. I have also tried by assigning design groups wit different cost/properties. Even in that case it is either violating velocities or the pressure in some pipes and junctions.
