If I check the line where you I the error:
https://github.com/OpenFAST/openfast/blob/0769598a17e19b3ccd00a85cde389995f55024a8/glue-codes/openfast-cpp/src/OpenFAST.cpp
Line 432,
hubShftVec[0] = cDriver_Input_from_FAST[iTurbLoc].pOrientation[0] ;
Which means that probably "pOrientation[0]" is wrong, since iTurbLoc should be ok since I just have a single wind turbine.
How can I act on pOrientation? Which term of the FAST input files is relevant here?
from sowfa.
A file turbineAlloc.0.txt is created and inside there is just:
Proc 0 loc iTurb 0 glob iTurb 0

Hi Enrico,
There doesn't appear to be anything obviously wrong with your ElastoDyn inputs. I did try running your model without external inflow from OpenFOAM (i.e., I changed CompInflow to 1) and noticed that your AeroDyn input is incompatible with the latest version of OpenFAST. I've attached an updated input file (renamed to permit uploading to github). Can you check to see if your model runs with OpenFAST alone?

Hi @ewquon,
I've run the case with OpenFAST alone and the changes you suggest and it works. However I've tried to run again windPlantSolver.ALMAdvancedOpenFAST and the error is still the same.
from sowfa.
Looks like the issue is caused by dryRun
being set to true in constant/turbineArrayProperties. This bypasses the calls to FAST and therefore leaves variables to be exchanged (in this case, cDriver_Input_from_FAST[iTurbLoc].pOrientation
) uninitialized.
from sowfa.
The problem now is in AeroDyn:

In the AeroFile (referenced in your .fst input file), a number of blade aerodynamics properties files are referenced. Does this file(s) exist in the same place as the AeroFile? I can recreate the error with your input files if the "AeroDyn_blade.dat" file is missing, otherwise the solver runs without issue for me.
from sowfa.
I checked the "AeroDyn_blade.dat" file and I found an uncommented line and NumBlNds was set to 19 but that extra line made the total to be 20.
The file was as it is in the OpenFAST/r-test folder on github:
r-test/glue-codes/openfast/5MW_Baseline/NRELOffshrBsline5MW_AeroDyn_blade.dat
The extra lines to be removed are 26-27:
!bjj: because of precision in the BD-AD coupling, 61.5m didn't work, so I changed it to 61.4999m

Hi guys,
I'm trying to run the 5MW NREL simulation too, but I'm having a similar error to the last one of @enricogussoni !!
It happens when OpenFast is launched in the OpenFoam simulation.
Here is the error:

I've also modified the AeroDyn_blade.dat file as enrico suggested. I've changed the density in file turbineArrayProperties to 1.225 as was set in AeroDyn15.dat. Still I don't know if there's to debug something in the input files or if it's completely another problem.
Thanks for any help!!
from sowfa.
Hallo, I had the same problem and I solved with the following
-AeroDyn15
-NREL5MWRef.0.fst
attached files, updated for OpenFAST:
note1: in turbineArrayProperties parameter nFASTSubSteps must be equal to deltaT (in controlDict) divided by DT (in NREL5MWRef.0.fst).
note2: of course delete line 26 and 27 from AeroDyn_blade.dat file.
