End-user Software License Agreement regarding PyWAsP
Licensee agrees to be bound by the terms of this Agreement, effective as of the date of Licensor’s distribution by e-mail to the Licensee of the necessary information to install and run the Software Package.
Whereas employees of the Technical University of Denmark, the Department of Wind and Energy Systems, have developed software called PyWAsP for the microscale downscaling of wind climates, which is under continual research development at DTU, as part of its extensive research within the field of wind energy;
Whereas Licensee wants to obtain an end user license to the PyWAsP Software – including a right to sub-license to Affiliated Entities - and Licensor is willing to grant such license;
Now, therefore the Parties have agreed as follows:
1. DEFINITIONS
1.1 The following definitions apply:
“Agreement” shall mean this multi-user software end-user license agreement.
“Documentation” shall mean the help files included within the Software Package
“Software Package” shall mean the PyWAsP software which consists of Python scripts and compiled libraries of the WAsP sub-modules, allowing them to be run via Application Programming Interfaces (APIs) in a flexible user-defined manner independent of the constraints of the WAsP graphical user interface. It should be understood that the Software is not "plug and play" and requires expert users.
“Licensee” shall mean the Company on the behalf of which the registered user accepts the terms of this Agreement.
"Affiliated Entities" shall mean in relation to Licensee, a legal person or entity belonging to the Licensee that Controls, is Controlled by, or is under common Control with Licensee. Control is direct or indirect beneficial ownership of fifty (50) % or more of the share capital, stock or other participating interest carrying the right to vote or to distribution of profits of Licensee, as the case may be.
“Licensor” shall mean Technical University of Denmark, Department of Wind Energy, Anker Engelunds Vej 1, DK-2800 Kgs. Lyngby, Denmark, Business Registration No. 30 06 09 46.
Licensee and Licensor are each hereinafter individually referred to as "Party" and jointly as "Parties".

END OF LICENSE TERMS
14. ANNEX 1 DESCRIPTION OF PyWAsP SOFTWARE, AND INSTALL AND LICENCING OPERATION
PyWAsP is a powerful software tool that allows users to easily access the functionality of WAsP, software for predicting wind resources of wind turbines in different terrain. With PyWAsP, users can easily integrate WAsP's powerful wind resource prediction capabilities into their own Python-based applications and projects. This allows users to take advantage of the advanced wind resource prediction capabilities of WAsP without using the Graphical User Interface of WAsP.
To install the software the following data is given by licensor to licensee:
• User ID and password for Conda package.
For the purpose of managing the licensing of PyWAsP the following data is given by licensor to licensee:
• License ID and activation token for the PyWAsP license server
• License server URL.
When PyWAsP is used by the licensee the licensee PyWAsP software will execute communication with the PyWAsP license server to verify the license and tally the number of runs and verify the number of points per run is within the allowed limits for the chosen subscription tier. See ANNEX 2 PRICE STRUCTURE. During this communication, the only information DTU will receive, in addition to the provided License ID and activation token, is the IP address of the system calling the server, for routine logging.
15. ANNEX 2 PRICE STRUCTURE
The PyWAsP pricing is based on a tier system, whereby 1-year subscription price banded according to the extent the licensee applies PyWAsP. The tiers are called Bronze, Silver and Gold. The features of PyWAsP are not altered by the tier level. The only difference is the number of runs and the maximum points per run.
The number of runs is the number of times a call to any of the functions get_site_effects(), get_site_effects_rose(), or FourierSpace.create_fourier_space() is made. There are additional functions in PyWAsP that call the get_site_effects functions, these include generalize(), downscale(), and generalize_and_downscale(), which calls it twice. FourierSpace.create_fourier_space is also called by create_lut(). The number of points in each run is the product of the west_east (NX), south_north (NY) and height (NZ) dimensions of the output_locs variable to each function, i.e. the number of points in each run is NX * NY * NZ.
Examples:
In order to calculate local effects on a grid 100 by 100 at 2 heights requires 100 * 100 * 2 = 20000 points. This would be possible with the Bronze Tier subscription.
In order to calculate local effects on a grid of 150 by 150 at 3 heights requires 150 * 150 * 3 = 67500 points. This would require the Silver Tier Subscription.
In order to calculate local effects on a grid of 300 by 300 at 4 heights requires 300 * 300 * 4 = 360000 points. This would require the Gold Tier Subscription.
An example of a run that goes beyond the Gold Tier Subscription would be a grid with dimension 400 by 400 at 5 levels, requiring 800000 points. In this case the run can be split into several smaller runs, thereby increasing the run count. Alternatively the licensee can approach the licensor to make a specific agreement.
The latest version of the pricing can be found in www.pywasp.dk. The pricing for a 1-year subscription starting in January 2023 is given below:
| Tier |
Bronze |
Silver |
Gold |
| Runs |
6000 |

16. ANNEX 3 PYWAsP DEPENDENCIES
PyWAsP relies on third party software components not included in the Software Package (Dependencies). Clause 2.7 and 8.6 refer to these dependencies. It is important that the licensees understand the implications of these clauses.
This annex gives information about how the user can find out about these dependencies.
Dependencies can be split into 2 types:
Direct dependencies: these are libraries that are explicitly called by the PyWAsP installed Python code.
Indirect dependencies: these are libraries that are called by the direct dependency libraries.
Indirect dependencies can be found by running the command 'conda list'.
An up-to-date list of direct dependencies can be found on docs.wasp.dk/pywasp. The list of direct dependencies as of January 2023 is:
- appdirs
- matplotlib
- netcdf4
- numpy
- pyproj
- python
- pyyaml
- rasterio
- scipy
- tqdm
- windkit
- xarray
