Basic Usage

Quick example

Open In Colab 
from epanet_plus import EPyT, EpanetConstants

if __name__ == "__main__":
    # Load an .inp file in EPANET using the toolkit class
    epanet_api = EPyT("net2-cl2.inp")

    # Print some general information
    print(f"All nodes: {epanet_api.get_all_nodes_id()}")
    print(f"All links: {epanet_api.get_all_links_id()}")

    print(f"Simulation duration in seconds: {epanet_api.get_simulation_duration()}")
    print(f"Hydraulic time step in seconds: {epanet_api.get_hydraulic_time_step()}")
    print(f"Demand model: {epanet_api.get_demand_model()}")

    # Run hydraulic simulation and output pressure at each node (at every simulation step)
    epanet_api.openH()
    epanet_api.initH(EpanetConstants.EN_NOSAVE)

    tstep = 1
    r = []
    while tstep > 0:
        t = epanet_api.runH()

        print(epanet_api.getnodevalues(EpanetConstants.EN_PRESSURE))

        tstep = epanet_api.nextH()

    epanet_api.closeH()

    # Close EPANET
    epanet_api.close()
