Adding new variables to .fst and .out files

[Mark.Spring]

In a parallel thread, I have mentioned that I am writing new code to implement tower wind loads due to aerodynamic drag.

Normal aerodynamic forces on the tower

Hi all, I’m Lorenzo Montanari, a PhD student of the University of Parma (Italy). I’m checking the wind turbine model, i’m writing in MATLAB language, with FAST. I’m considering the data of the 1.5 MW wind turbine you used to verify FAST. I don’t find the data file to insert the drag coefficient and the geometrical parameters of the tower’s elements that need to calculate the normal aerodynamic forces along the tower’s height due to the wind! How does FAST evaluate the normal aerodynamic forc…

I need to output all the external loads applied to the tower. I propose to add internal time-dependent signals to FAST.OUT.

WIth respect to replies on this thread to Alec’s questions about adding new output signals, I would like to run the MATLAB script, but cannot find it in the FAST release. Please can you (1) tell me the name of the file, (2) tell me where it is in the FAST release or (2) send me a copy? Thanks.

Kind Regards,

Mark
