getHubShftDir error

[gantech]

Filing an issue on behalf of Enrico.

I'm running example cases from SOWFA (latest version from gitHub) and I'm not able to solve an error.
What I'm trying to do is to run windPlantSolver.ALMAdvancedOpenFAST in example.ALMAdvanced using precursor data from example.ABL.flatTerrain.neutral. The mesh and the precursor are ok, changeDictionary.updateBCs.west worked, but the solver crashes after few seconds with the log message that you find below. The problem seems to be in

fast::OpenFAST::getHubShftDir(std::vector<double, std::allocator >&, int)

but I don't know how to act on getHubShftDir. Can you check if I'm wrong or not and help me?

Thank you
Enrico G.from Politecnico di Milano (Italy)

An MPI process has executed an operation involving a call to the
"fork()" system call to create a child process. Open MPI is currently
operating in a condition that could result in memory corruption or
other system errors; your MPI job may hang, crash, or produce silent
data corruption. The use of fork() (or system() or other calls that
create child processes) is strongly discouraged.

The process that invoked fork was:

If you are absolutely sure that your application will successfully

by setting the mpi_warn_on_fork MCA parameter to 0.

Here is the link to Dropbox 7z file with turbine data and .fst>
https://www.dropbox.com/s/ez55oi4redh0gzp/EnricoGussoni_exampleALMadvanced.7z?dl=0

[enricogussoni]

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?

[enricogussoni]

A file turbineAlloc.0.txt is created and inside there is just:

Proc 0 loc iTurb 0 glob iTurb 0

[ewquon]

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?

AeroDyn15.dat.txt

[enricogussoni]

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.

[ewquon]

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.

[enricogussoni]

The problem now is in AeroDyn:

[ewquon]

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.

[enricogussoni]

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!!

[SebastianoStipa]

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.
