We are interested in writing a wrapper for TurbSim that allows us to smoothly stitch together multiple wind timeseries that are generated from TurbSim. For instance, I want to generate a 1-hr timeseries with an avg wind speed of 10 m/s and then I want to add a second hour where the avg wind speed is 12 m/s. The question is making the transition between these timeseries physically representative. I'm wondering if anyone within NREL has done this previously or if there are some hidden features within TurbSim v2.0.0 that could enable this to happen.
I understand from another topic that you can generate periodic files by
Simply set TurbSim input UsableTime to the string, "ALL" and run TurbSim to generate periodic wind data files useable by FAST.
It seems like in making it periodic, you have constrained the timeseries such that U(t=0) == U(t=end). Perhaps this can be extended such that U(t=0), U(t=end) can be specified by the user, but I know there will be issues in ensuring that the statistical properties of the wind profile are kept.
Thanks for the help!
