Using EPANET-Matlab-Toolkit

clear all; close all;

% Load paths
start_toolkit;

% Load file
d = epanet('test.inp');

% Get link node indices # from node to node
indices = d.getLinkNodesIndex;

% Return initial length of pipes
d.getLinkLength

% Fixed length of pipes
for link_ind = 1:d.LinkCount
    ind_Node1 = indices(link_ind, 1);
    ind_Node2 = indices(link_ind, 2);
    
    [latlons] = d.getNodeCoordinates([ind_Node1, ind_Node2]);
    
    X = [latlons(1, :);latlons(2, :)];
    fixLength = pdist(X, 'euclidean');
    
    d.setLinkLength(link_ind, fixLength);
end

% Rerurn link lengths
d.getLinkLength

d.saveInputFile('fixLengths.inp');

% Unload dll
d.unload;
