Hello, everyone
This is the first time I am posting in this forum. I am a Masters student from India and I am a beginner in FAST. So I have been trying to model a DeepCWind with point absorbers configuration around the DeepCWind. While running fast, I encountered this error. Please help me out.

I have tried changing the grid dimensions in the Turbsim File, but every time I increase the grid dimensions, the position in the wind file coordinates becomes even larger resulting in the FF wind array boundaries violation. And also I face a new error which is:
ED_HD_InputOutputSolve: HydroDyn_CalcOutput: Angles in GetSmllRotAngs() are larger than 0.4 radians
FAST encountered an error at simulation time 41.113 of 3600 seconds.

How do I solve this?
