I am sorry I do not know which generator model is used in CART WT. Maybe someone else can you with that.

Best regards.

Hi again, Thank you for sharing your scripts. I was refering to the surface plot .m script but thanks for more detailed explanation maybe someone else can benefit from them. Best regards. Edit: I see that you are trying to get gain scheduling for pitch controller. I have used "Advanced Control ...

Dear OpenFAST team and users, I have generated Cp surfaces for different wind speeds for my turbine model and I wanted to know if my results are OK. Can you please comment? I used 30 simulations per windspeed and I set all degrees of freedom in elastodyn files to 'false'. each simulation had a diff...

Dear Dr.Jason Thank you for your reply. I think I have found the mass matrices. If anyone need it they are located inside the 'admout.txt' interim result file and also stiffness matrices are located inside the 'kout.txt' file. Best regards, Deniz Edit: I was mistaken. It was not the mass matrices fi...

Hi, I am trying to obtain my 6x6 mass and stiffness matrices through NuMAD. NuMAD output is designed for FAST7 I guess and I can only obtain ElastoDyn input files through it. While looking for the interim output files in NuMAD, I find the stiffness matrices. However, non-diagonal terms in these matr...

Dear Dr. Jason,

Thank you I was able to import multiple linearization files at the same time.

Best regards,

Dear Dr. Jason, Thank you very much for your reply. I was able to obtain the "D" matrix. I was reading https://www.nrel.gov/docs/fy17osti/67015.pdf and at pg.12 I saw that for every 10 deg rotation a linearization is made and matrices are azimuth-averaged. Right now I can use fx_getMats.m ...

Hi, I am trying to obtain aerodynamic power sensitivity to rotor-collective blade pitch. Reading through NREL 5MW paper I see that it is obtained through linearization process in OpenFAST. I cannot seem to find any output of it in linearization file. Is it obtained through another process after the ...
