Re: Sending RtAeroPwr via ServoDyn to Bladed-Style DLL Controller

Hi Bonnie, Thank you very much for your helpful answer. The missing link of the code with the new FAST_types.f90 files was one problem in my version that I would not have found by myself. So, thanks for giving the hint on testing this. Additionally, I had one other mistake at one call of my modified...

Sending RtAeroPwr via ServoDyn to Bladed-Style DLL Controller

Dear all, In order to develop and test a controller for a variable speed, stall controlled wind turbine, I need the current rotor aerodynamic power RtAeroPwr at each time step being available in a Bladed-Style DLL controller. I am using OpenFAST v2.1.0. and followed the instructions for passing para...

Re: Available output channels from MoorDyn module

Hi Matt, Thanks for your fast answer. I think I'm indeed looking for the line-end forces, because I'm interested in the vertical force component of the mooring that acts on a floating platform to check some hydrostatic calculations. So, to my understanding, the sum of the fZ forces of all fairleads,...

Re: Available output channels from MoorDyn module

Hi Matt, I have a similar problem as Antonio. I'm trying to output the vertical force at node 20 of line 1. According to the MoorDyn user guide I thus defined an output L1N20fZ in the MoorDyn input file. However with this setting FAST crashes. I have tried this with FAST v8.16 and OpenFAST v1.0.0., ...

Blade Tip Brake in FAST

Hey, I would like to simulate a small wind turbine with blade tip brakes in FAST/OpenFAST. According to the Guide to Changes in FAST v8 the ability of modelling tip brakes is a feature not included in FAST v8 so far, but it was part of FAST v7. I haven't found any information on this feature for Ope...

Re: Gain Scheduling

Dear Jason, thank you very much for taking the time to debug my model. It's great to have such a good support here. Furthermore I'm a bit relieved that I didn't waste your time with something caused by my misunderstanding oder wrong usage of FAST. Concerning the gain sheduling problem, do you think ...

Re: Gain Scheduling

Dear Jason, Thank you very much for your quick reply. From reading your comments I think you have a really good understanding of my issues. Initialisation processes could be a good reason for the zeros/spikes at time zero. I thought about that, too. Unfortunatly, I also have no idea why there are sp...

Re: Gain Scheduling

Hello all, like Harald and Ville I currently also try to calculate and replicate the values in Table 7-1 from NREL/TP-38060 for the blade pitch control PI-gain scheduling values. However in contrast to them I am using FASTv8.16 and have some troubles with the necessary linearization. Let me first ex...

Re: Geometric Properties of the NREL 5-MW baseline blade

Dear Jason, thank you very much for your answer and sorry for the late reply. Your hint was really helpful, as I was now able to calculated the values of BlCrvAC and BlSwpAC based on your information. For that I used the values for PitchAxis and AeroRef given in your post from Sat Jan 29, 2011 4:28 ...

Geometric Properties of the NREL 5-MW baseline blade

Hallo, I currently try to retrace the definition of the blade properties used for the NREL 5MW Reference Wind Turbine. In specific I would like to understand where the values given in the CertTest\5MW_Baseline folder of the FAST v8.16 archive come from. As mentioned in the report "Definition of...
