Hello,
My question is regarding the TURBSIM GP LLJ model and the coherent turbulence files generated and coupling them with FAST. Reading the various user guides I understand that when using the GP LLJ model the coherent turbulence is contained in the .cts file. In the TURBSIM user guide it says that Aerodyn v12.57 to v13 can read this file with the .bts file and add them together.
I’d like to simulate turbines experiencing a LLJ using FAST but understand that FAST uses inflowind for the wind files which doesn’t seem to have the capability of reading in .bts .cts files to include the coherent turbulence in the wind field. I also see that aerodyn v15 is used in FAST v8 is there a previous version of FAST where I can use Aerodyn v13 and input the windfiles (.bts and the .cts)?
Alternatively would it be possible to manually write code that can sum the two .bts and .cts files and create a wind file that would be compatible with FAST (or Bladed) like .bts or .wnd?
Thank You
George
