How to generate synthetic models and assign diameters within WaterNetGen:
  1. Generate a new (synthetic) model;
  2. Import a pipe catalogue (use the suppyed example catalogue) and customize it (if need);
  3. Assign pipe type & class to the pipes (Select all pipes <CTR+A> | Right Click, click "Selected Pipes"  + "Pipe Type ..." on popup menu);
  4. Assign water demand to nodes (click on "Load demands" button);
  5. Run pipe sizing procedure;
  6. Save Project.

2015-05-27 update:
  • Leakage simulation: add pipe leaks (background & burst) parameters to the "Group Edit" menu.
