I was asked by a reviewer to add the Fatigue Loads at the tower base, blade root, and drivetrain. I have simulated three different controllers on the NREL 5-MW OC4 Semi-sub FOWT. What is the best way to do it and present it? I have downloaded the MCrunch but it is not clear for me how to use it.
Thank you for your help
Dear @Michel.Owayjan,
OpenFAST can certainly calculate time-variations of tower, blade, and drivetrain loads that can be post-processed into fatigue. Fatigue is often expressed as a damage-equivalent load (DEL), which can be calculated by both MCrunch and MLife. That said, simply computing the standard deviation of the time series is often a reasonable proxy for a DEL.
Best regards,
