1 year ago Take a look at issue #1484. In particular this comment: https://github.com/OpenFAST/openfast/issues/1484#issuecomment-1588255529
Closing as this is identical to a previous issue.

Dear all， The following error occurred when I was running the 15MW wind turbine model:

OpenFAST encountered an error during module initialization. Simulation error level: FATAL ERROR
Aborting OpenFAST.
This error appeared after I set up the visualization file，My settings are as follows：
---------------------- VISUALIZATION ------------------------------------------ 2 WrVTK - VTK visualization data output: (switch) {0=none; 1=initialization data only; 2=animation} 1 VTK_type - Type of VTK visualization data: (switch) {1=surfaces; 2=basic meshes (lines/points); 3=all meshes (debug)} [unused if WrVTK=0] False VTK_fields - Write mesh fields to VTK data files? (flag) {true/false} [unused if WrVTK=0] 10 VTK_fps - Frame rate for VTK output (frames per second){will use closest integer multiple of DT} [used only if WrVTK=2]
His error report here points to the HydroDyn file, and I'm not sure what went wrong. I will upload my file to the attachment, any help would be appreciated.
