Dear Jason,
I adjusted my BeamDyn blade input file. I first ran my model in standalone BeamDyn and worked well. now I coupled BeamDyn and FAST. I also updated source code of AeroDyn based on the link [url]https://github.com/NWTC/AeroDyn[/url] and discussion in [url]Problem running Test18.fst in Simulink by Changing TMax using FAST_8.16 - #4 by Jason.Jonkman]. using of {AFAeroMod=2,TwrPotent=0,SkewMod=2, UAMod=3 } in AeroDyn 15 and WindType=1 in inflowWind, the BEMT problem still remained (see BEMT_Error.jpg).
by setting airfoil aerodynamic model to steady model, negative Vx problem appears (see BEMT_Error2.jpg).
please do you have some idea about this new issue?
Best regards,
