Error in running 02_ccblade.py

[GBA217]

I'm trying to tune the controller for a 80m diameter 2MW turbine and when I run 02_ccblade, I get this error:

Writing rotor performance text file: c:\Users\xxxx\ROSCO\Examples\examples_out\02_Cp_Ct_Cq.Ex03.txt

I have a few questions regarding this.

1. If I have not generated a cpctcq curve before for the model, what do I give as input for "rotor_performance_filename" in the .yaml file? I provided the path to NREL-2p8-127_Cp_Ct_Cq.txt. Will that work? Or can I leave that input blank?
2. Is aerofoil corrdinates file mandatory when I'm tuning th econtroller for the first time? It is mentioned that Numcoords can be set to zero if coordinates not included. Does that mean that it is not necessary for the simulation?
3. What could cause the above mentioned error?

.yaml file that I used:

1. Any input for the performance_filename should work. This example will generate a new one.
2. I don't think the airfoil coordinates are necessary.
3. I'm not sure what causes this error. I will ask the WISDEM team.

[ptrbortolotti]

hello, the error is most likely caused by some issue with the input files. can you maybe share your setup?

[GBA217]

Hello @ptrbortolotti,
Yes, I figured that the issue is coming from the brent function calculation as the residual BEM solver residual is failing to reach zero in the iterative solver (please correct me if I'm wrong). Below is the setup:

Hello, I'm sorry but I don't really understand what's going on from this text. I talked to @dzalkind and our recommendation is to go back to a working example and start changing things one by one. It looks like you've changed the airfoil polars. Maybe start there, as things could easily go wrong in those tables. Please let us know if and when you find the issue

[GBA217]

Hello @ptrbortolotti, the issue was indeed with the polars list. The order was messed up in the aerodyn input file. Thanks
