Next Generation Wind Turbine Design and Simulation
The QBlade Software
QBlade is a highly advanced multi-physics code that covers the complete range of aspects required for the aero-servo-hydro-elastic design, prototyping, simulation, and certification of wind turbines.
QBlade allows you to run highly detailed simulations of any wind turbine design, with superior physics models more than 20x faster than real time. All this functionality is made accessible in an intuitive and friendly graphical user interface.
The stand-alone QBlade software is available for Windows and Linux operating systems and is offered in two releases for non-commercial and commercial application. Use QBlade for:
- Wind Turbine Design (HAWT, VAWT & Multi-Rotor)
- Floater Design and Numerical Testing
- Controller Testing and Tuning
- IEC Design Load Certification
- Windfarm Simulations / Wake Interaction Studies
- Digital Twins in Python or Matlab Environments
Quick facts
A constant and driving force during the whole software development process is to make wind turbine design and simulation effortless, fun and accessible to everyone.
Sophisticated User Interface
QBlade comes with a fully featured GUI for pre- and post processing using a custom developed dynamic graph class. In addition, all simulations are beautifully rendered in 3D real time visualizations.
Ultra Fast Performance
QBlade leverages the current computer architecture by utilizing CPU and GPU parallelization techniques in an efficient low level C++ implementation for an unprecedented numerical performance. Full aero-servo-hydro-elastic wind turbine simulations at more than 30x real time speed!
Highly Versatile Formulation
QBlade can be used to design and simulate custom wind turbine designs, on- or offshore. Create and simulate custom tower, floater or jacket based turbines with single- and multi-rotor designs, vertical- or horizontal axis.
Advanced Numerical Models
QBlade employs state-of-the-art and beyond robust numerical models - such as free vortex wake aerodynamics, non-linear corotational beams and second order hydrodynamics for an unparalleled accuracy.
Dual License Scheme
QBlade is available as a free public "Community Edition" for academic users and as an optimized & extended "Enterprise Edition" with dedicated support and training packages for commercial users.

QBlade Community Edition VS. Enterprise Edition
QBlade is released in two versions: the public Community Edition “QBlade-CE” and the commercial Enterprise Edition “QBlade-EE”. The Enterprise Edition of QBlade includes several essential, practical and timesaving addons and improvements for a production-ready application by commercial users, such as automation, scripting and dramatically increased performance. A feature-based comparison between both versions is shown in the table below:
| Feature | QBlade Community Edition | QBlade Enterprise Edition |
|---|---|---|
| License Type | Academic Public License | Commercial License |
| Commercial Use Allowed | no | yes |
| Included software training | no | yes |
| Support | user’s forum | dedicated on-demand support |
| Source Code Avaliability | public | closed |
| Aero-Hydro-Elastic Modelling | yes | yes |
| Wind and Wave Generation | yes | yes |
| Graphical User Interface | yes | yes |
| Text Based Object Import and Export | yes | yes |
| Software in Loop (SIL) Interface | yes | yes |
| Modal Analysis, Campbell Diagram, Aeroelastic Power Curve | no | yes |
| Higher Order Particle Wake Aerodynamics | no | yes |
| Multi-Rotor Turbine Design | no | yes |
| Multi-Turbine Windpark Simulations | no | yes |
| IEC Compliant DLC Preprocessor (61400-1, 61400-2, 61400-3, 61400-2-3) | no | yes |
| Command Line Interface & Batch Automation | no | yes |

Frequently Asked Questions
Is QBlade Open Source?
The source code is publicly available, but strictly speaking, no. Since the release of QBlade 2.0 we have changed from the GPLv2 license to the Academic Public License (APL) . This means that the software and source code of QBlade are freely available to the public - but are restricted to non-commercial use only. While for non-commercial use the APL resembles the GPL license, allowing for free modification and redistribution of the code under the APL, commercial users need to aquire a commercial license to use the software.
Do I need a license to use QBlade?
This depends on how you want to apply the software. In a commercial, or non-commercial setting. In any case the APL release can by used by anyone for evaluation purposes. Find out more in the License Information section.
Can I run QBlade on my Mac?
At the moment QBlade is only available for Windows and Linux. However, in general it can be cross-compiled for Mac-OS. In the near future we will also release a Mac version. Stay tuned until the Mac version is available in the Downloads section.
Can I use my old project files (.wpa) with QBlade 2.0?
Unfortunately - no. We have made the decision to cut the compatibility with old releases in favor of a much cleaner code base. However, with our vastly extended import functionality you should have no problem to get your data inside QBlade 2.0. Have a look at the Data Objects Import and Export section in the docs.
Where can I get support for QBlade?
Have a look at the Documentation first, if you dont find an answer check out our QBlade Forum. For commercial users we are also offering dedicated training packages and on demand remote support and troubleshooting.
Is QBlade on Github or Gitlab?
For now the official live repository is not available online. However you can download the QBlade-CE source code of the latest release from the Downloads section. We are very open to contributions - if you want to contribute just send us a mail request to . If you encounter a bug or find error there is a dedicated section in our Forum for bug reporting.
