Hi everyone,

I have been playing around with openfast lately and have stumbled upon a problem for which I have not found an answer on this forum hence my post (apologies in advance if this has already been posted though…).

I would like to generate a 3,900s time series, the first 300s of which I would not considered in the post-processing part due to transients. For the last 3,600s, I would like to have a specific average wind speed (say 10m/s) at hub height and a specific turbulence intensity (say 6%).

At the moment, my understanding is that we can only specify the mean wind speed and turbulence intensity for the whole duration of the Turbsim file (e.g. 3,900s rather than 3,600s).

I think I have found a workaround by running 7,200s and throwing the first 3,600s but this is quite a loss of resources…

Would anyone have a more elegant solution to this problem?

Thanks in advance,

Bruno Nguyen.
