Problem running NREL 5MW Test files

Hello I am new to the forum and I just started using FAST (version 7) and I have few problems with running FAST. I have downloaded the NREL 5MW test files from the

wind.nrel.gov/public/jjonkman/NR … Bsline5MW/

site. I build the necessary wnd files with using TurbSim. I used the 90m_12mps_twr.inp file from FAST v8 as the input file. Now when I try to run NREL 5MW test files, I get the following errors with the NRELOffshrBsline5MW_Floating.fst after setting

1.0 GBRatio - Gearbox ratio (-):

because it complained about GBRatio has to be set to 1.0…

 Aborting FAST.

Dear Andre,

A similar question has been answered in the following forum topic: FAST (particularly my Apr 06, 2011 post).

Here is a link to FAST v7.02.00d with the interface to Bladed-style DLLs: wind.nrel.gov/public/jjonkman/FA … erface.exe.

Best regards,

Many thanks for the alternative executable. Now the 5MW test files run but I get the following error:

 Aborting FAST.

hello,

Maybe you can view how much time you set up in your primary input file and wind input file.You must keep your time of simulation larger in wind input file than in the primary input file.if not,the error happened!This my understanding! Maybe it can help you !

Ruiliang.Wang

Here is the time in the wind input file:

Dear Andre,

After I see what you have set up in the wind input file,I find the question.I think you should change the Usable Time to 630.it can’t be less than TMax.

Hope it can help you !

Best Regard

Ruiliang.Wang

I redid the wnd file with T = 630 and the same DT as in the fst file and now the simulation completes. Many thanks for the heads up.

The NRELOffshrBsline5MW_Floating.fst file works for me now but it throws out a warning:

So I be worried about the results here?

Dear Andre,

The small angle assumption violation warning has been discussed several times on this forum, for instance here: NREL 5MW controls (DLL interface).

Best regards,

Many thanks for the link.

Is it possible to compile the BladedDLLInterface into the MATLAB/Simulink version of FAST, e.g. the S-Function using MinGW32 and not the Intel FORTRAN Compiler?

Andre,

I have never tried to use any GNU compiler with Matlab. A quick scan of the Matlab documentation shows that they do support GNU compilers for Linux/Mac but not Windows. It’s possible you could get it to work, but if you don’t have experience making Matlab mex functions, it’s probably a difficult task.

It works partly but gfortran complains about not finding some of the matlab routines but this is because of case-sensitivity.

Hello,

I am using fast v.8 with the “test 18.fst”, if I do not change any input I do not have any problem, but if I change the “TMax” to 100 I get the same error as it is explained at the beggining of this topic;I have tried to do what it is expalined, increase the “usable time” at the “90m_12mps_twr.inp” file but I get the same error. what is hapenning?

I do not know exactly how does it work, because the “NRELOffshrBsline5MW_Onshore_AeroDyn.dat” file calls to “90m_12mps_twr.bts”, but I have changed the .inp file since I can nor read the other file, so maybe the problem is here.

I have attached the .fst and inp files as .txt,( I will attach the .bts within other post)

thank you, best regards.

Hello again,

I solved the problem!

thank you.

Hello,

I have started using FAST8, and I have just tried to run the 5MW wind turbine model, but the following message appears:

Could you help me fixing it, please?

Regards,

Iñaki

Dear Inaki,

Your problem sounds identical to the one solved recently in the following forum topic: ERROR RUNNING FASTV8.

The land-based version of the NREL 5-MW turbine is available as Test18 in the CertTest of FAST v8.

Best regards,

Dear Jason,

first of all, thank you for your time. However, now I have some problems trying to run the Test18. When I run it, it starts running correctly, but it finds some kind of error and the following message appears:

I think it is related to the ServoData folder, but I am not sure. I would be so grateful if you could help me solving this problem.

Dear Inaki,

Running Test18 with the 64-bit version of the FAST v8 executable requires the use of a 64-bit version of the Bladed-style DLL controller (you can’t mix 32- and 64-bit addressing schemes). Change “DISCON_Win32.dll” to “DISCON_x64.dll” in the ServoDyn input file.

Best regards,

Dear Jason,

it works now. Thank you very much.

Regards,

Iñaki
