Loopnet is an open-source software for the simulation of water distribution networks based on EPANET 2.1 from Open Water Analytics. Loopnet focuses on speeding up the simulation, for which purpose it diverts from EPANET 2.1 in two main aspects:
It uses the loop method (or looped Newton-Raphson method) for the solution of the hydraulic simulation non-linear systems. Compared to the Global Gradient Algorithm used in EPANET, the loop method generally leads to significantly smaller linear systems, thus potentially speeding up the simulation.
It uses OpenMP to take advantage of current multicore processors in order to further speed up the hydraulic simulation.
Loopnet was developed as part of the doctoral thesis of Fernando Alvarruiz Bermejo, under the supervision of Profs. Fernando Martínez Alzamora and Antonio M. Vidal Maciá, from the Universitat Politecnica de Valencia (Spain).
We would like to take this opportunity to acknowledge the work of Lewis A. Rossman (@LRossman), as the original developer of Epanet, and of Open Water Analytics, as maintainers of the Open Source Epanet Initiative.
