Dear Dr. Jonkman,
I try to calculate the moments of inertia for the RNA of an onshore reference turbine (130-3.4MW, see nrel.gov/docs/fy19osti/73492.pdf). Therfore, I followed the steps described in post http://forums.nrel.gov/t/ansys-model-tower/1722/4. I converted the input files of the WT to the FASTv7-Format.
I created the following files:
130_lin.fst
130_AD.ipt
Blade_NoDamp.dat
Tower_NoDamp.dat
Platform.dat
Linear_130.dat (Control)
When I run the .fst-file I get an AeroDyn error:
I checked the AD.ipt-file but I cannot find the problem.

Regarding the error message, I am not sure what is meant by “AeroDyn element table”. I assume it is the table at the end of the file? I hope my desription is sufficient to comprehend the problem.
Thank you very much in advance!
