Re: Blade nodes in BeamDy and ElastoDyn

Hi, I have an additionol question to be sure i understand it correct. In the ElastoDyn summary file are the interpolated blade properties. In my case I set in ELastoDyn the teo parameters like this: 100 BldNodes - Number of blade nodes (per blade) used for analysis (-) 6, 15, 34, 43, 52, 62, 71, 82,...

Disable function that stops the simulation at tower strike

Hi, I do not want that FAST is abording the simulation when a tower strike happens. It should complete the simulation. In which files are which changes are necessary? I searched for "tower strike" in the files and only found it in Aerodyn.f90 and AeroSubs.f90 I hope someone can help me! Be...

Re: Bladed 4.4 dll controller in ServoDyn v1.03

Dear Sachin,

I have two questions:

1. Is your model running whitout the controller?
2. You have a Bladed >4.4 controller or Bladed <4.4 controller

Best regards

Re: Comparison between Bladed and OpenFAST - blade loads

Hello, if somebody have the same issue. The problem was, i compared to different coordinatesystems! Blade 1 Loads: Root axes, 0m (Bladed) = "RootFxb1, RootFyb1, RootFzb1, RootMxb1, RootMyb1, RootMzb1" Blade 1 Loads: Root axes with Twist, Node 1> 0m (Bladed) = "Spn1FLxb1, Spn1Flyb1, Sp...

Re: Comparison between Bladed and OpenFAST - blade loads

Hi, In both simulations the acceleration of gravity is 9.81 m/s^2. The blade mass and the rotor mass moment of inertia in the Elastodyn summary are equal. The tilt is also equal. The shear is in both simulations 0. Do you have other parameters to check? The four other channels are mostly the same. F...

Comparison between Bladed and OpenFAST - blade loads

Hello, I am comparing Bladed and OpenFAST (ElastoDyn). Can some tell me the issue for the higher range (oscillation) of the Blade loads after reaching rated power? I think, My is the result of the higher Oscillating Fx, but why is Fx oscillating higher? I generated a power curve, here are the result...

Re: Blade nodes in BeamDy and ElastoDyn

Hi,

is it right when I have a blade with a length of 54m and BldGagNd is 9 that the nodes are on following points:

BldGagNd [-] Bladelenght [m]
1 3
2 9
3 15
4 21
5 27
6 33
7 39
8 45
9 51

Re: Initial pitch with bladed-style dll

Hi,

do you remember this topic https://wind.nrel.gov/forum/wind/viewtopic.php?f=4&t=23?

I change the file to use pitchrates and it is running very well. But what change is necessary to can start with an initial angle?

Best regards

Re: Initial pitch with bladed-style dll

Hi,

I already changed the line "dll_data%avrSWAP(10) = 0" to "dll_data%avrSWAP(10) = 1" in the file "BladedInterface.f90". Or what change do you mean?

Best regards

Re: Initial pitch with bladed-style dll

But how can it be overwritten when I am using pitchrates to change the pitchangle? I am setting only the following channels: avrSWAP(55) = 0 ! Pitch override: 0=yes avrSWAP(35) = 1 ! Generator contactor status: 1=main (high speed) variable-speed generator avrSWAP(56) = 0 ! Torque override: 0=yes avr...

Initial pitch with bladed-style dll

Hi, I would like to know how i can start with a initial pitch angle when i am using bladed-style dll? I am not using the method of sending pitch angles to the actuator. Rather i am using pitch rates. Everything is working fine. But i do not know how i can start with a initial pitch angle. When i set...
