Published models
This section offers several models that can be downloaded and directly opened with the latest version of Ashes
1 DTU 10-MW isolated blade
The DTU 10-MW blade constrained at the root, as a cantilever beam.
The model can be downloaded on this link: simis.io/downloads/open/Published models/DTU 10-MW isolated blade.ash
2 DTU 10-MW onshore
The full DTU 10-MW reference wind turbine including the tower and the control system (using the basic DTU controller). No reference monopile is given in the specification document, therefore an onshore model is provided.
The model can be downloaded on this link: simis.io/downloads/open/Published models/DTU 10-MW onshore.ash
3 IEA 15-MW isolated blade
The IEA 15-MW blade constrained at the root, as a cantilever beam.
The model can be downloaded on this link: simis.io/downloads/open/Published models/IEA 15-MW isolated blade.ash
4 IEA 15-MW
The full IEA 15-MW reference wind turbine including the tower, the monopile and the control system (using the ROSCO controller).
The model can be downloaded on this link: simis.io/downloads/open/Published models/IEA 15-MW.ash
5 Multirotor
A four-rotor wind turbine. This model is inspired by the Vestas multirotor concept, but is not meant to be an accurate representation of it.
The model can be downloaded on this link: simis.io/downloads/open/Published models/Multirotor.ash
6 NREL 5-MW isolated blade
The NREL 5-MW blade constrained at the root, as a cantilever beam.

9 OC4 Phase I
The NREL 5-MW offshore reference wind turbine mounted on the OC4 jacket. This model is used in the OC4 Phase I test.
The model can be downloaded on this link: simis.io/downloads/open/Published models/OC4 Phase I.ash
10 OC4 Phase II
The NREL 5-MW reference wind turbine mounted on the OC4 semi-submersible. This model is also available in the Ashes starting window.
The model can be downloaded on this link: simis.io/downloads/open/Published models/OC4 Phase II semisub.ash
11 Gyroscope
A gyroscope in no gravity with no aerodynamic loads. This model is used to simulate gyroscopic precession and was used in this video: https://www.youtube.com/watch?v=pRwrMESDJK4
In order to get the gyroscope to spin, we recommend applying a prescribed moment on node 21 in the z-direction of a magnitude of 40 000 Nm, and to disable the load after 3 seconds. This is illustrated in the figure below:

12 Multirotor 2
A 9-rotor wind turbine, inspired by the HAW-Hamburg multirotor
