Error:‘GF wind was exhaust’ when using OLAF with turbulent wind

Dear all,
When I applied turbulent wind files generated by turbsim and OLAF to simulate IEA 15MW UMaineSemi, the following error occurred.

here is my OLAF file settings:

The same turbulent wind file was used to simulate a 15MW UMaineSemi with BEM, and no such error was reported.
I would like to know the possible causes of this error.

Best regards,

Dear @He.Li,

Which version of OpenFAST are you using?

There are a couple of puzzling things with the error message. The message states (trying to access data at NaN seconds). IT_Lo=-2147483647, IT_Hi=-2147483646. The concerning thing is the NaN seconds, and the indices that given for IT_Lo and IT_Hi are negative. This may indicate a bug in the wind retrieving calculations, but without knowing exactly which version of OpenFAST you are using, I can’t say for certain.

Regards,

Dear @Andy.Platt ,
I used OpenFAST v3.5.1 and the controller is ROSCO-v2.8.0.
Best regards,

Dear @He.Li,

My apologies for the delay in replying. You may have already found a solution to your problem, but if not, there may be a bug in OLAF that will need addressing.

We recently posted a release version 3.5.2 with some minor bug fixes, but I don’t think any new bug fixes for InflowWind or OLAF are included.

Regards,
