I am trying to optimize a hydraulic network in watergems using darwin designer. But I am getting an error "Feasibility check failed. No feasible solution exists with current input data". Steady state analysis is being used. Although I am able to analyse the network with pre-defined pipe diameter. Could anyone please help me out?
