WANDA can simulate transport of liquids and gasses and has dedicated functionality for heat and multi-species transport (slurry), for ship locks and real time (operational) control of pipeline networks. The software can be linked via open standards to other applications, e.g. for operator training purposes and to operational systems, e.g. for real-time control.
WANDA has been licensed world-wide to many well-known pipeline operators, design engineers, consultants and universities. WANDA can be applied in a variety of professional areas, such as: oil & gas pipeline systems, drinking water networks, fire fighting and sewage systems, waste water treatment plants, hydropower installations, thermal energy grids and cooling water systems.
WANDA has been developed by Deltares (formerly: WL | Delft Hydraulics) since the 1970’s. It is designed by engineers that use this software product in their own consultancy and research projects. It has been tested and validated extensively in our in-house testing facility.
The WANDA architecture provides scientific access to various domains such as liquid and gas transport, heat transfer, and multi-phase systems. These domains are covered by dedicated WANDA modules. For all modules the WANDA user interface is consistent and identical. Working with WANDA is easy to learn and intuitive.

Deltares offers for WANDA several license packages that comprise different domain related functionality and different rights of use. Please check the packages at the bottom of this page.
WANDA License Packages differ in terms of functionality and in the number of user licenses. A license is issued after a one-off payment of license package costs and has unlimited validity. Both stand-alone and server licenses are possible, using a hardware key (dongle) or mac address lock. Together with the purchase of a License Package you obtain a 12-months release subscription and a dedicated number of hours support.
When purchasing multiple identical license packages, we offer a volume discount. With the second license package the discount is set at 25%, with the 3rd and 4th at 50% and from the 5th package the discount is set at 75%.
The WANDA License packages are made available through the WANDA Wiki site. To get access to the download section you need a wiki-account. Account log in will be provided after purchasing a WANDA License Package. If your organization has already purchased WANDA the log in information has been sent to the main WANDA contact within your organization.
Deltares also offers temporary WANDA licenses, such as free trail and lease. Please check the support tab for further information.

Modeling & Analysis
The hydraulic design of pipeline systems during different operational phases is a complex task due to the dynamic behaviour, which is inherent to pipeline systems. A thorough understanding of the hydraulic behaviour of the system is therefore essential to obtain a proper design that guarantees safe operation and minimal costs for construction and maintenance.
WANDA provides powerful design tools to support the hydraulic design from the first schematic diagrams to the evaluation of the control loops during emergency events. Primary subjects to evaluate and optimize a hydraulic design are:
- flow capacity, flow velocity & flow distribution
- cavitation, water hammer and dynamic behavior
- pressure and safety analysis
- pump efficiency, system characteristics
- real time control and control induced pressure waves
WANDA’s intelligent components and user-friendly interface enable you to carry out any hydraulics analysis intuitively and efficient.
The engineering mode supports the engineer with the most common activities in hydraulic design of piping systems. WANDA engineering mode allows the steady state flow conditions (stationary flow) to be researched. The engineering mode allows for:
- Component selection for flow and pressure balancing
- Pipe diameter selection, using head loss calculations and hydraulic gradient analysis
- Reduction in energy usage of pumping stations
- Definition of preferred pump characteristics by a system’s analysis
The transient mode allows unsteady flow conditions to be investigated, e.g. during start-up, pump trip and control actions. The transient mode allows for:
- Varying pressure and discharge analysis
- Assessment of operational measures
- System’s bottleneck analysis to apply e.g. surge towers, air vessels and pressure relief valves
- Extended time simulations
WANDA computes all transient phenomena, including water hammer reflection, line packing, cavitation with variable vapour pressure, temperature-dependencies (WANDA Heat), quasi-steady heat transfer and complete thermodynamic gas behavior (WANDA Gas). The cavitation model used has been validated in a laboratory-based experimental facility (with a total length of 1400 m) and in the field.
WANDA user interface is simple and intuitive. Hydraulic components such as pumps and valves can be selected from a gallery and placed into a worksheet. The hydraulic properties of a component can be specified in a property input sheet. Calculations can be interrupted, assessed and resumed. Detailed information of the flow like pressure and discharge can be viewed at any location in the system at any moment in time. Some other features are:
- Intuitive look and feel based on iGrafx Flowcharter®
- Copy and paste of components, diagrams, graphs, tabular results and input parameters
- Text and background on different layers (diagram, text, background)
- Details or subsystems separated with the connector-tool
- Spread sheet view to compare input/output properties
- Comparison of complete cases with case-compare
- Animation function (movie) helps to analyse wave propagation and reflection
- All property names can be translated into the user’s language
- Various unit systems are supported, as well as a user defined unit system
With the Wanda Engine module, the numerical core of WANDA can be linked to other applications via the OpenMI (Open Modelling Interface) standard. OpenMI is a standard especially designed for coupling of numerical models by organizations leading in water management. Using external software such as MATLAB® or LabVIEW®, WANDA can be coupled to operator training software, real-time control or mechanical control systems. The possibilities are infinite.
The Wanda Data-AcQuisition (WanDAQ) module provides a communication link between a WANDA model and a PLC. This link allows a PLC to be tested in isolation from the rest of the control system. Using this principe, the PLC of a pumping station can be tested without the problems that come with the normal site acceptance tests. With WanDAQ, you’re not dependent on the weather or flow into the pumping station, safety concerns or time restraints. Also, the WanDAQ module allows the user to test all scenario’s, including the most extreme cases. This greatly reduces the costs and increases the scope of site acceptance tests.
