[0003] The establishment of the topology structure of the original method is limited to the planar pipe network. When the pipe network is complex, such as the ring pipe network, multi-source pipe network, and asymmetrical structure of the water supply and return pipe network, the original method cannot realize the flow simulation of the whole network.
