Problems with running FAST.Farm

Open Yongbyon opened this issue 1 year ago • 1 comments

image image No matter how I change NY_Low and Y0_Low, it always reports the error Farm_Initialize:AWAE_Init:AWAE_UpdateStates:InflowWind_CalcOutput:CalculateOutput:IfW_FlowField_Ge tVelAcc:Grid3DField_GetCell: Violation of GF wind array boundary: Y-direction grid is too small. Y=510; Y boundary = [-500, 500] InflowWind_CalcOutput:InflowWind_GetSpatialAverage:CalculateOutput:IfW_FlowField_GetVelAcc:Grid3DF IfW_FlowField_GetCell: Violation of GF wind array boundary: Y-direction grid is too small. y=500.82; Y Boundary = [-500, 500] The values reported as errors also stay the same, why is this?

Your answers are much appreciated!

Dear @Yongbyon,

It looks like your TurbSim grid extends from Y= -500 to 500 m. However, both your low-resolution domain and your high-resolution domains for turbines 6 and 8 have Y dimensions that extend beyond 500 m. The TurbSim grid must fully cover the FAST.Farm domains.

FYI: Given the complexity of the FAST.Farm modeling guidance for ambient inflow generation and its compatibility with the low- and high-resolution domains of FAST.Farm (https://openfast.readthedocs.io/en/main/source/user/fast.farm/index.html), we generally recommend using the python scripts available in the OpenFAST_Toolbox (https://github.com/OpenFAST/openfast_toolbox/tree/main/openfast_toolbox/fastfarm) when setting up the ambient wind inflow and low- and high-resolution domains used by FAST.Farm.

Best regards,
