Hi @Jason.Jonkman:
I am getting an error in TurbSim that I have never got before.
It occurs when I change the Grid height to 280 m and above. Even when I use 279.5 m it works fine. This is the error:
Running TurbSim (v2.00.07a-bjj, 14-Jun-2016).
Reading the input file “150m_88mps_wind_shearJCS1r.inp”.
Calculating the spectral and transfer function matrices:
** u-component matrices (IEC coherence method)**
** v-component matrices (identity coherence)**
** w-component matrices (identity coherence)**
** Generating time series for all points:**
** u-component**
** v-component**
** w-component**
** Computing hub-height statistics**
forrtl: severe (157): Program Exception - access violation

I have entered my own wind shear profile. Please let me know if you know what could have caused this error and how I could fix it. Ideally I would like to enter a GridHeight of 295 m.
Thank you.
