Invalid numerical input for file

Hey there,

after a while I am getting back to work with FAST, finally. Thus, I have compiled OpenFAST on my ArchLinux system and try to run some old simulations where the input files have been written to be used with FAST v8.16. However, as recommended in[https://wind.nrel.gov/nwtc/docs/README_OpenFAST.pdf The input file for AeroDyn has been updated to include now the lines needed by OpenFAST:

False         CavitCheck	  - Perform cavitation check? (flag) TRUE will turn off unsteady aerodynamics
     103500   Patm		 - Atmospheric pressure (Pa) [used only when CavitCheck=True]
       1700   Pvap	         - Vapour pressure of fluid (Pa) [used only when CavitCheck=True]
         .5   FluidDepth         - Water depth above mid-hub height (m) [used only when CavitCheck=True]

But when trying to run OpenFAST with different input files which have been working on FAST 8.16 before the same error occurs:

$ openfast .../Load-Cases-Nantes/LB/DOWEC_6MW_LB_Test03a_Steady_12mps_DLL.fst

  Aborting OpenFAST.

I think there is an error in the file path or something similiar, caused by switching from windows to linux because the errors do not make sense to me as the respective files seem to be correct. Can these errors occur when OpenFAST ist not capable of finding the respective files?

Best regards,
Daniel

Dear Daniel,

From your error message, my guess is your AeroDyn primary input file is formatted improperly. As with any input file format problem, I suggest that you use the Echo option from the primary AeroDyn input file to debug errors in the input-file processing.

Best regards,

Dear Jason,

thank you for your reply. I have tried different configurations with the Aerodyn-files I have gotten from Paul (who is out of office for a while) and applied the changes he suggested me to incorporate to make the Aerodyn-files working with OpenFAST. It seems that I have overlooked something because still I am experiencing that error, that OpenFAST is expecting different values than found in the Aerodyn file. Thus, I have to dig deeper to find the error. I will give feedback after finding it.

Best regards,
Daniel

Dear Jason,

I have found a number of errors (specific lines missing) in AD input file, as there have even more lines been added within the latest AD update. E.g the lines

======  Dynamic Blade-Element/Momentum Theory Options  ============================================== [used only when WakeMod=2]
          2   DBEMT_Mod          - Type of dynamic BEMT (DBEMT) model {1=constant tau1, 2=time-dependent tau1} (-) [used only when WakeMod=2]
          4   tau1_const         - Time constant for DBEMT (s) [used only when WakeMod=2 and DBEMT_Mod=1]

Were not there in former AD input file versions. Thus, even when WakeMod=1, AD was looking for these lines.

Best regards,
Daniel

Dear Daniel,

Yes, these lines where added with the inclusion of dynamic BEMT (DBEMT) in OpenFAST v2.0.0.

Best regards,

Dear Jason,

when/where can I download OpenFAST v2.0.0? I’m trying to run test 26 of the 5MW baseline turbine, but I get also this message:

I’m not sure where does the CavitCheck parameter go on the AeroDyn15 input file.

Many thanks in advance!

Greetings,

Natalia

Dear Natalia,

OpenFAST v2.0.0 is available here: github.com/OpenFAST/openfast/releases.

CavitCheck should be on line 12 of the primary AeroDyn v15 input file. But as with any input file format problem, I suggest that you use the Echo option from the input file to debug errors in the input-file processing.

Best regards,

Dear All,

This is my first message to the community. It’s good to be here.

I’m just simply trying to execute onshore wind turbine certification test, which is already available with the “Test18.fst” file under Certest directory of FAST. I’m not compiling.
I’m trying to understand the NRELOffshrBsline5MW_InflowWind_12mps.dat file. I’m able to execute analyses successfully under steady wind condition (WindType=1), turbulent wind condition- by using bts input file -(WindType=3).
Fatal Error occurs under uniform wind conditions (WindType=2). Error message is:

"

uniform wind file, but the first data line does not contain the proper format.

a FAST encountered an error during module initialization.
Simulation error level: FATAL ERROR

Aborting FAST.
"

I haven’t changed anything in the source file coming from zipped FAST folder. “Filename of time series data for uniform wind field” is “Wind/90m_12mps_twr.bts”.

For now I think that the problem arises from the .bts file which is for Turbsim _ AeroDyn analyses. At that moment, do I need a uniform wind file with .hh extension? I have checked the FAST directory but can not see an .hh file.

Do you have any idea?
Sincerely,

Mustafa

Dear Mustafa,

WindType=2 in the InflowWind module of FAST v8 and OpenFAST requires a simple text-based wind data file. Please see my post dated Mar 05, 2014 in the following forum topic where I provide an example of a uniform wind file with wind-speed steps: http://forums.nrel.gov/t/beginner-guide-for-matlab-simulink-and-fast/761/12. Please note that what were formerly called AeroDyn “hub-height” wind files are called “uniform wind files” in the InflowWind module of FAST v8 and OpenFAST.

Best regards,

Dear Jason,

This solution is also clear in the InflowWind Manual. I appreciate for your help.

Sincerely,

Mustafa

Dear Jason ,

I am trying to run FASTv8 since is the version my university has been working on for the last years. I have successfully ran FAST when I set the Wavemod to 0 but as I want to analyse the response of waves, I am getting this error in hydrodyn and I still have not found the reason why, here is the message error:

I have looked into the HydroDyn input file and I have seen the option WvSumQTF (without an ‘F’ as shown in the error message), so I have no clue where can be the mistake. I would appreciate any help.
Thank you very much,
Best regards,

Dear @Alvaro.Ponce,

Have you enabled Echo in the HydroDyn input file? What does the Echo file show?

Best regards,

Dear Jason,

Thank you for your rapid answer, yes the Echo file shows the following:

From what I interptertrate there is a problem when HydoDyn is reading WvDiffQTFF but I am not sure why this is happening.

Thank you again ,
Best wishes,
Álvaro

Dear @Alvaro.Ponce,

There should be header line between WaveElevyi and WvDiffQTF. It appears that the header line has been deleted from your input file. The header line normally says:

---------------------- 2ND-ORDER WAVES ----------------------------------------- [unused with WaveMod=0 or 6]

Does adding this header line solve your issue?

Best regards,

Dear Jason,

Unfortunately, adding the header does not solve the issue, I have tried with another HydroDyn input file and the error that I am getting is different due to not enough memory when allocating arrays. So for now, I will just try to use the different Hydrodyn input file in a computer with more memory and use FAST_x64 instead, and then adapt the changes from the original input file.

Thank you very much for your help,
Best regards,
Álvaro

Dear @Alvaro.Ponce,

I think I’d have to see the HydroDyn input file and associated echo file to comment on why the formatting is not correct.

I generally agree that a 64-bit executable is mandatory when running well-resolved FAST/OpenFAST models with HydroDyn enabled.

Best regards,

Dear Jason,

Dear @Alvaro.Ponce,

You’ve shared the Echo file associated with the OpenFAST primary input file, not the Echo file associated with the HydroDyn input file. Moreover, you have Echo set to FALSE in your HydroDyn file, so, this Echo file is not generated anyway. Can you set Echo to TRUE in your HydroDyn file, generate the Echo file, and share it?

Best regards,

Dear Jason,

Dear @Alvaro.Ponce,

It looks like you are missing the line 26 in your HydroDyn input file, where WvKinFile is specified. This line should look like:

“” WvKinFile - Root name of externally generated wave data file(s) (quoted string) [used only when WaveMod=5 or 6]

Not having this line in your HydroDyn input file causes HydroDyn to abort when processing the input file.

Best regards,
