Deltares is pleased to announce the release of Wanda 4.1.2. This release fixes several issues that have been discovered since the release of Wanda 4.1.1. The following issues have been resolved:
- Resolved issue for incorrect computation of initial air volume under some circumstances.
- Resolved issue for delayed output of TAB component when simulating large number of timesteps.
- Improved error handling in parameterscript.
- Resolved issues for Venturi component.
- Resolved issues for Channel component.
- Resolved issues for Collector component.
- Added velocity calculation for Orifice component.
- Improved error handling and messages during steady state initialisation.
The new setup is available from the Downloads & Patches wiki page
Wanda 4.1 (released on August 13th, 2012) included a bug that was not discovered during testing. This issue can cause incorrect behaviour of some Liquid components, especially Vent (air valve) and Weir components.
We have fixed the problem and a new setup is available from the Downloads & Patches wiki page.
If you’ve downloaded and installed Wanda 4.1 between August 13th and September 6th, please download the new setup and reinstall the software. Installing the Patch is sufficient in this case.
You can check the version numbers of Wanda on your PC. The following versions are affected:
- User interface version: 4.1.1084
- Wanda executables version: 4.1.03
Deltares is pleased to announce the release of Wanda 4.1. This release brings us a new module: Wanda Heat.
If you have not ordered Wanda 4 yet and want to upgrade, please contact our sales team: sales@deltaressystems.nl
Changes in Wanda 4.1 – Highlights
- New module: Wanda Heat
- The Wanda parameter script has been improved
- Importing of EPANET models has been improved
- Solved a bug that caused the control valves to remain closed after valve closure
- Added “allowable pressure ratio” (cavitation characteristic) as an output series for the valve and control valves.
Changes in Wanda 4.0.2 September 2011
The following issues have been resolved since the release of Wanda 4.0.1 July 2011:
- The visibility of output properties for H-nodes in the diagram was saved incorrectly. Visibility of H-node output properties wasn’t saved correctly (checkbox in output field) and therefore the value was not updated in the diagram when the output data changed.
- The visibility of output properties in the diagram was saved incorrectly
- The visibility of the quantity property of the SENSOR component in the diagram was saved incorrectly
- Incorrect mean efficiency calculation in Pump characteristics
- Incorrect power calculation in Pump characteristics
- Incorrect efficiency calculation in PumpEnergy module
Note: these issues only affect Wanda 4 and are not applicable for Wanda 3.73
Changes in Wanda 4.0 July 2011
The following changes have been made since the first release of Wanda 4.0 vs. May 2011:
- Bug fix in the pressure calculation in the H-node. An H-node with more than 1 connected PIPE (with different diameters) showed the incorrect minimum pressure. The Wanda 4 manual has been updated with a clear definition of the pressure in the H-node (Section 4.4). An erratum of the manual pages 4 - is available from the wiki http://wanda.deltares.nl.
- Improved numerical stability of Tee, Y and cross junction components.
- Improved messages and error handling of steady state computation. If the steady state solution is not converged after the specified number of maximum iterations, the steady message report is displayed automatically. An error message has been added and the debug information with the 20 last solution vectors has been removed.
- The handling of an unstable solution (a solution with changing behaviour of an H-component, the so called reciprocating phase change) is improved. The user gets an error message when an unstable steady state solution is found.
- For both errors (Converging and Stability) it is allowed to start the unsteady simulation. The model may converge further during the unsteady simulation (do not specify any action for a couple of time steps).
Deltares is pleased to announce the availability of Wanda 4.0 Liquid. This version is the first official release in the Wanda 4 series and improves the stability and functionality of Wanda. Wanda 4.0 is available via the Downloads & Patches wiki page.
New features include:
- The architecture of Wanda has changed significantly, allowing for new modules such as Heat and Gas and supports, besides the existing suppliers and fall types, components with more than 2 hydraulic connect nodes
- New 3 and 4 connect node components like Tee, Y and cross junctions for accurate local head loss calculations
- New optional component "Turbine" with wicket gate

Wegens grote belangstelling voor de Wanda Introductie cursus op 24 November (inschrijving is inmiddels gesloten) organiseert Deltares een extra introductie cursus op 10 December 2009.
Deze cursus is bedoeld voor gebruikers die nog geen of weinig ervaring hebben met het gebruik van WANDA.
Tijdens de cursus wordt zowel de Wanda User-interface als algemene modelleringsaspecten behandeld. De workshop geeft de gebruiker de kennis en ervaring om een leidingsysteem uit de praktijk te vertalen naar een numeriek model.
De workshop heeft een zeer interactief karakter, vragen en feedback worden ten alle tijden op prijs gesteld.
De volgende onderdelen worden besproken
- Userinterface:
- hydraulisch schema tekenen
- invoeren van eigenschappen
- raadplegen van uitvoer (grafieken en tabellen)
- Weerstandsberekeningen (Module Engineering)
- Samengestelde grafieken maken van pomp en leidingkarakteristieken
- Simulaties (waterslagberekening) (module transient)
- Toelichting belangrijkste hydraulische componenten
- Modelleringsaspecten - vertaalslag van praktijk naar model
- inleiding Control module
De cursisten maken door middel van presentaties en interactieve opdrachten kennis met de functionaliteit van Wanda. De cursus is gericht op de praktische toepassing van Wanda en is uitermate geschikt voor beginnende gebruikers, ook als deze nog geen ervaring hebben met hydraulische modellering.
U kunt zich aanmelden voor 1 november middels bijgevoegd inschrijfformulier.
Due to some recent developments, a new version update to Wanda 3.71 has been released.
The new setup is available via the Downloads & Patches wiki page.
Improved in Wanda 3.71h
Issues found since Wanda 3.71g (released on October 10th, 2009).
- Pressure ratio is not calculated in steady states for control valves if initial state is other than 'position'
Due to some recent developments, a new version update to Wanda 3.71 has been released. This version is also compatible with Microsoft Windows 7 and 64-bit systems.
The new setup is available via the Downloads & Patches wiki page.
