Issure for coupling running SOWFA and openFAST2.6.0 as "example.NREL5MW.ALMAdvancedFAST8"

[chatianming]

I install the SOWFA and openFAST 2.6.0.
I have some problems when I run the case named "example.NREL5MW.ALMAdvancedFAST8", becaue the case named "example.NREL5MW.ALMAdvancedFAST8" is for fastV8, so I copy the relevant files in r-test2.6.0 and mend the .fst.
All my files are uploaded in attachment.
Could you give the case that can be running if possible, very thank you.
best wishes
the errors are as follow:

I would recommend doing a test run of your modified FAST input files with standalone openfast (you'll need to set CompInflow in the .fst from 2 to 1, and give an appropriate InflowWind input). After you've verified that that is working, then the next thing to check is your turbineArrayProperties and make sure the inputs being passed to OpenFAST are reasonable.

Very thank you, and I want to confirm that the SOLVERS of "pisoFoamTurbine.ALMAdvancedOpenFAST" completly installed. So I really need a complete case to test the solvers of "pisoFoamTurbine.ALMAdvancedOpenFAST" coupled of 2.4.x and openFAST 2.6, but the case in the GitHub is for fastV8, so could you upload a complete case to help me to test the solver.

in addition, I also want to know how to run a openFAST2.6 case in the linux system? where should I find or compile those files such DISCON_glin32.so for openFAST2.6 in Linux ?

very thank you!

You can find an example controller here: https://github.com/OpenFAST/r-test/tree/main/glue-codes/openfast
Or you can use a more general generic controller from here: https://github.com/NREL/ROSCO

Unfortunately, we don't have the bandwidth to support any of these old codes, so I don't have any test cases to share. Given that this is open-source, you should look at https://github.com/NREL/SOWFA/tree/master/src/turbineModels/turbineModelsOpenFAST/horizontalAxisWindTurbinesALMOpenFAST to help resolve any issues you encounter at runtime.

If you use https://github.com/NREL/SOWFA-6/tree/dev, we have more up-to-date turbine ALM coupled to OpenFAST.

@ewquon I want to confirm whether the current SOWFA does not support the operation of beamdyn module. When I set CompElast in the.fst file to 1=ElastoDyn, the coupling case can run. But when I set it to 2=ElastoDyn + BeamDyn for blades. It starts with the following error:
Running BEM.

I want to confirm is whether the error is caused by the use of the beamdyn module.I checked the horizontalAxisWindTurbinesALMOpenFAST in the make/options .It contains the beamdyn library
-laerodynlib \
-lbeamdynlib \
-lelastodynlib
I look forward to hearing from you. Thank you very much
