Change .wnd file using FAST & LabVIEW

Wind & Water Computer-Aided Engineering Software Tools
1

Hello,

I’m working with FAST v7.02.00d-bjj, LabVIEW 2012 and LabVIEW Real-Time 2012, using the FAST&LabVIEW demo interface and a Desktop PC converted with LabVIEW Real-Time Module.
The project works fine with NRELOffshrBsline5MW_Onshore.fst, NRELOffshrBsline5MW_AeroDyn.ipt and the others demo input files, with StepWind.wnd.
If I try to edit NRELOffshrBsline5MW_AeroDyn.ipt to change the reference to the .wnd file input, choosing one of the test provided with FAST or one generated with the tool TurbSim v1.06.00, the project doesn’t work because the real-time target disconnects.
I also try with different .fst file and related input files, with the same results.
I correctly upload the input files in the real-time device and I also rightly change the reference in the RT init FAST.vi in every test.
How can I change the .wnd file correctly?

Best regards,
Andrea.

Hi Andrea,

I can try to help. I’m first curious if you can find any log or error files being produced (in my system, they would show up in the ni-rt directory on the RT unit). If I had to guess, there is an unhanded FAST exception or error occuring, maybe the wind file isn’t located or named correctly, or doesn’t have adequate size for the turbine etc. The best thing to do would be to try to find an output or error file which can help narrow down the problem. Hope this helps!
