FAST.Farm

Open ILDENIEL opened this issue 1 year ago • 9 comments

Hello everyone, I'm trying to run FAST.Farm but an error occurred. Before downloading the newest version I've used version 3.4.1 and FF ran without any problem. image

OpenFAST v3.5.2 runs smoothly as always, what could be the problem? Thanks in advance

For compliteness https://github.com/OpenFAST/openfast/issues/2010#issuecomment-1924534167 At this link it is possible to find the problems with the previous version of FAST.Farm. For this reason I tried with FF v3.5.2.

Dear @ILDENIEL,

I'm not sure I understand. Are you saying a FAST.Farm model that runs without issue in OpenFAST v3.4.1 triggers a stack overflow error when running in OpenFAST v3.5.2? If so, can you share the full set of input files for both versions? If not, please clarify.

Best regards,

Dear @jjonkman, Yes this is what I meant. In this folder you can find all the files I'm using, in particular

  • in the folder 341 you can find the fst, fstf and iw files for version v3.4.1
  • in the folder 352 you can find the fst, fstf and iw files for version v3.5.2
  • in the other folder there're all the ED,AD and IW files.

versions.zip

Thanks for your support.

Thanks for the set of input files. @jjonkman confirmed that it isn't an obvious configuration issue, so there is a bug in the code someplace causing the stack overflow. I will take a look at it and report what I figure out.

Thank you for your support @andrew-platt @jjonkman, I will continue using FF v3.4.1 for now. Best regards

It seems like version 3.5.1 does not have this problem, but 3.5.0 and 3.5.2 have. Just FYI.

We think this is fixed with #2118. Please reopen if you have issues with v3.5.3 (will be posted later this week).

This apparently was not fixed with #2118 as the issue still exists in the 3.5.3 release.

My dear I had the same stack overflow issue(https://forums.nrel.gov/t/fast-farm/1887/484) with a low wind speed wind farm calculation ,and i fixed the issue by rolling back the Fast.farm version to 3.4.1 Best regards Farm.zip
