Hi Sam,
The version of TurbSim in the OpenFAST repository (github.com/OpenFAST/openfast/issues/176. I can send you the alpha archive of TurbSim if you need it; just let me know.
By the way: even if you are not using FAST / OpenFAST simulations, I would expect similar software (Bladed, HAWC2, OrcaFlex, etc.) would have the same issue regarding use of Taylor’s frozen turbulence assumption.
Best regards,
