Re: Tendon failure in FAST modeling

Dear Jason and all, I am trying to implement a transitional event of mooring line loss for DTU 10MW floating model. Based on the inputs from this discussion I have tried to modify the source code for MoorDyn but the result is not as expected. Could anyone correct me where I am going wrong? P.S. Rela...

Re: DTU 10-MW Reference Wind Turbine

Dear Jason and all, LIFES50+ D1.2 states that, AeroDynv14 calculates the unsteady aerodynamics at fixed initial position rather with the moving tower. For a floating wind turbine the tower moves along with the floater and initial position for aerodynamics calculation is actually a frame of reference...

Re: Modelling of a 10MW FOWT

Dear Yajun, The free decay motions that you are experiencing could be because of the initial platform displacements given in the ElastoDyn. Try to verify static condition with all initial displacements zero. If the outputs of platform displacements are having non-zero values means the coupled struct...

Re: Surface visualization of DTU-10 MW

Dear Ghaith and Jason,

Correct me If I'm wrong. Surface visualization is possible only with AeroDynV15. Where as the github repository doesn't contain AeroDynV15 inputs.
Is there any updated files for the structure? Any suggestion on this are appreciated.

Kind regards

Re: Taut leg mooring synthetic ropes

Hello everyone, I am trying to implement synthetic ropes on DTU 10MW structure using MoorDyn. (out of the context from this thread, I guess) When trying to find initial nodal positions, so that can add connection points further, around 30+ nodes are positioned higher than the fairlead node. The simu...

Re: DTU 10-MW Reference Wind Turbine

Dear Jason and all, Can anyone explain why the electrical output is facing with such numerical instabilities? The frequency of the fluctuations seems not resulted from wind shear, tower shadow (3P-effects) and does not match with the wave frequency as well. Any suggestions are appreciated. Thanks an...

Re: DTU 10-MW Reference Wind Turbine

Dear Jason, When I tried to run the model operation DLCs provided in the repository there are no problems with the DTU controller. I till cant figure out the error in my setup. As you mentioned could be a mistake in the directory. The dtu_we_controller_bladed is running with the feedback loops from ...

Re: DTU 10-MW Reference Wind Turbine

Dear Jason, Yes, previously I worked with the NREL 5MW baseline mounted on WindFloat semi submersible structure and the simulations went smooth except unsteady aerodynamics(as AeroDynv15 cant assume Beddoes-Leishman dynamic stall yet). Now, I have implemented the dtu_we_controller that I took from D...

Re: DTU 10-MW Reference Wind Turbine

Dear Jason,
Both the FAST executable and Master controller are 32-bit and the file directory is also in order.
I am facing the error "the DISCON procedure could not be loaded", as for my knowledge it is a Command in ServoDyn.
Any suggestions would be helpful.

Re: DTU 10-MW Reference Wind Turbine

Dear all, I am working on DTU 10MW for offshore that mounted on OO-star semi floater with mooring lines. Main agenda is to study the dynamic response of mooring system. When running with the newly developed DISCON_IEA_offshore.dll , facing the following error. Faced the same error even when working ...
