How to generate synthetic models and assign diameters within WaterNetGen:

Generate a new (synthetic) model;
Import a pipe catalogue (use the suppyed example catalogue) and customize it (if need);
Assign pipe type & class to the pipes (Select all pipes <CTR+A> | Right Click, click "Selected Pipes" + "Pipe Type ..." on popup menu);
Assign water demand to nodes (click on "Load demands" button);
Run pipe sizing procedure;

Save Project.

2015-05-27 update:

Leakage simulation: add pipe leaks (background & burst) parameters to the "Group Edit" menu.

2015-02-15 update:

Update the "EPANET Energy" formula

2014-07-02 update:

"Load demand" bug correction.

2014-05-30 update:

Pressure-driven: includes a new "Insufficient pressure" warning - flagged when the nodal pressure is below its reference value.
Pressure-driven change: pipe background leakage is assigned 50% to each pipe end-nodes.
Join and append models (with merging of common nodes & deletion of parallel pipes).

2014-01-31 update:

Upgrade of the sizing procedure.
New tables/charts, mainly related to the leakage simulation results.

2013-10-04 update:

Added the capability to record (and save to .avi file) an Extended Period Simulation.

Some notes about EPS recording:

This capability is still in development...
The user must select a compression method, for example, the CINEPAK (it is already included with windows);
Play the file using Windows Media Player.

2013-07-01 update:

Pipe leakage data available at the EPANET interface level (graph, table and as a node/link property);

Include a menu item to check for updates.

2013-04-20 update:

Bug correction (assign initial diameter from catalogue);
Bug correction (change diameters based on maximum velocity allowed).

2013-04-09 update:

Hydraulic solver uses the LDL^Tnumerical factorization instead of the Cholesky ( LL^T) factorization;
Allow to open Epanet 2.0 (.inp, .net) projects;
Now save Epanet projects with a new extension (.wng) to avoid the overriding of the original (.Net) project.
Some minor updates in catalogue editor (roughness field).

2012-11-18 update:

Pipe Sizing update (simulated annealing changes)...

2012-02-15 update:

Pipe Sizing update...

2012-01-26 update:

Pressure-driven simulation update (improved convergence...)

2012-01-19 updates:

Includes more (Performance related) run-time data
Corrected some bugs

2011-12-12 updates:

New pipe catalogue with commercial diameters
Corrected some bugs related with pipe-sizing
Update optimization module
Update pressure-driven simulation module
Update user-interface (visualization of pressure-driven results)
