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.

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.

6 NREL 5-MW isolated blade 

The NREL 5-MW blade constrained at the root, as a cantilever beam.

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:
