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