Compatibility with openFAST and ElastoDyn #7

Closed ahmedhassan554 closed 2 years ago

ahmedhassan554 commented 2 years ago

Hi, I want to use Sandia's SNL61p5m for 5MW baseline in openFAST. When I changed blades in elastoDyn from "NRELOffshrBsline5MW_Blade" to "FASTBlade_precomp", the following error comes up "Invalid numerical input for file. unable to read NB1InpSt". I have two questions.

  1. Is openFAST compatible with these files e.g FASTBlade_precomp?
  2. If not, what is the solution so I can use this blade configuration for my simulation?

Hi ahmedhassan554,

I think the error you are facing is due to a file format mismatch. This is common when various tools by different sources are in rapid development.

Assuming you are using the most recent version of OpenFAST (v3.1.0) and referring to the NREL 5MW r-test blade file as an example, you can solve this by commenting out:

  1. Line 25 of writeFastBlade.m file.
  2. Line 30 of writeFastBlade.m file.

Please let me know if this solution works for you.

p.s I am not a developer of NuMAD nor a part of Sandia National Labs, but have extensively used the older version of NuMAD (v2) in my research and would like to contribute back to the community.

Dear Mayank, Yes, it does work!!. Thank you so much. Just a side note that you can delete directly the 1st and 6th line from the .dat file.
