ENinitH: Initialize hydraulic engine

In epanet2toolkit: Call 'EPANET' Functions to Simulate Pipe Networks

Initialize hydraulic engine

Description

ENinitH Initializes storage tank levels, link status and settings, and the simulation clock time prior to running a hydraulic analysis.

Usage

ENinitH(flag)

Arguments

flag	A two-digit flag indicating if hydraulic results will be saved to the hydraulics file (rightmost digit) and if link flows should be re-initialized.

Details

Call ENinitH prior to running a hydraulic analysis using ENrunH and ENnextH.ENopenH must have been called prior to calling ENinitH. Do not call ENinitH if a complete hydraulic analysis is being made with a call to ENsolveH. Values of flag have the following meanings:

00	do not re-initialize flows, do not save results to file
01	do not re-initialize flows, save results to file
10	re-initialize flows, do not save results to file
11	re-initialize flows, save results to file

Set flag to 1 (or 11) if you will be making a subsequent water quality run, using ENreport to generate a report, or using ENsavehydfile to save the binary hydraulics file.

Value

Returns NULL invisibly; called for side effect
