Hi @Jason.Jonkman,
I am getting an error in a TurbSim model that I am trying to simulate.
I am using a user-defined wnd shear profile. I would like to create a wind-field for the 5MW DeepCwind turbine. The hub-height is 90 m and so I have set GridHeight to be 175 m and GirdWidth to be 300 m. I have set NumGrid_Z and NumGirid_Y to be 15 x 15. I use the general coherence model with CohExp of 0.85. I have shown the TurbSim file and the Shear Profile below.
I am getting the following error:
Reading the input file “90m_wind_shearJCS1-12.inp”.
- Calculating the spectral and transfer function matrices:*

Can you help me to fix this please ?
Thank you.
