Hey there,
after a while I am getting back to work with FAST, finally. Thus, I have compiled OpenFAST on my ArchLinux system and try to run some old simulations where the input files have been written to be used with FAST v8.16. However, as recommended in[[url]https://wind.nrel.gov/nwtc/docs/README_OpenFAST.pdf[/url] The input file for AeroDyn has been updated to include now the lines needed by OpenFAST:
False CavitCheck - Perform cavitation check? (flag) TRUE will turn off unsteady aerodynamics
103500 Patm - Atmospheric pressure (Pa) [used only when CavitCheck=True]
1700 Pvap - Vapour pressure of fluid (Pa) [used only when CavitCheck=True]
.5 FluidDepth - Water depth above mid-hub height (m) [used only when CavitCheck=True]But when trying to run OpenFAST with different input files which have been working on FAST 8.16 before the same error occurs:
$ openfast .../Load-Cases-Nantes/LB/DOWEC_6MW_LB_Test03a_Steady_12mps_DLL.fst

FAST encountered an error during module initialization.
Simulation error level: FATAL ERROR
Aborting OpenFAST.I think there is an error in the file path or something similiar, caused by switching from windows to linux because the errors do not make sense to me as the respective files seem to be correct. Can these errors occur when OpenFAST ist not capable of finding the respective files?
Best regards,
Daniel
Edit: Unfortunately I got an http error while attaching the input file. Thus I am posting it here:
