Dear Ruiyang.He,
OpenFAST does not directly output the TI, but you can output the wind velocity at user-defined points from InflowWind as you describe, and then calculate TI (standard deviation divided by mean wind speed) in a post-processing step.
Dear Wang Jundong,
FAST.Farm doesn’t currently track or output the ambient or disturbed (ambient + wakes) wind velocity at locations along the wake planes. However, you can output the ambient and disturbed wind speeds at points in the low-resolution domain by using the WηVAmbδ and WηVDisδ outputs in the FAST.Farm OutList. Moreover, you can output the disturbed wind velocity at XY, YZ, or XZ cross planes of the low-resolution domain or output the full ambient and disturbed velocity field across the low-resolution and all high-resolution domains via the outputs in the VISUALIZATION section of the FAST.Farm input file.
Best regards,
