Next Generation Wind Turbine Design and Simulation
The QBlade Software
The brand new QBlade 2.0 software is a highly advanced multi-physics code, that covers the complete range of aspects required for aero-servo-hydro-elastic wind turbine design, prototyping, simulation and certification.
QBlade has been in development for more than 10 years following a modular implementation of highly efficient novel aerodynamics, structural dynamics and hydrodynamics solvers in a modern, object-oriented C++ framework.
The release of QBlade v2.0 marks a major milestone – offering the capabilities for advanced modeling and simulations of offshore floating wind turbine designs to everyone.
The stand-alone QBlade software is available for Windows and Linux operating systems (MacOS coming soon) and is offered in two releases for non-commercial and commercial application.
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.
QBlade Community Edition VS. Enterprise Edition
QBlade is offered 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:

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.
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.
