Dear @3sdb, It doesn't look like your FAST.Farm model is set up properly. All aerodynamic nodes of each OpenFAST model must remain in the bounds of their respective high-resolution domain for the entire simulation. There may be others, but one obvious error I see is that you've set We generally recommend using the OpenFAST toolbox (https://github.com/OpenFAST/openfast_toolbox/tree/main/openfast_toolbox/fastfarm) when generating inflow and setting up FAST.Farm input files to ensure that you are following the FAST.Farm modeling guidance: https://openfast.readthedocs.io/en/main/source/user/fast.farm/ModelGuidance.html.
