Re: Replacement for RunNTM?

1. Yes 2. Using the Matlab toolbox, I think the following code should do what you want. It reads the primary TurbSim file called 'TurbSim.inp' , sets the wind speed to 5 m/s, and writes a new TurbSim file called 'NewTurbSimFile.inp', using the format in a template TurbSim file called 'TurbSim_templa...

Re: FAST Error FORRTL

My guess is that the controller you are using (or some other part of the code that didn't come from NREL) is trying to read from a file named 'U:\git\VAero\windturbineframework_mreich\fort.86', which doesn't exist.

Re: Problem in Running fx_mbc3 and fx_getMats

I have run the Matlab code with the file you attached, and it runs. I did notice a problem with how it reads the rotating frame column (i.e., it assumes nothing is in the rotating frame with this version of the .lin file), so I've submitted a pull request for that here: https://github.com/OpenFAST/m...

Re: Access violation reading location

I suspect that the code isn't linking with the new compiled version of the FAST_types.f90/ElastoDyn_Types.f90 files, which is what causes the access violations. (I have had this problem before, myself. I am not sure if this is a Visual Studio problem or if there is something wrong in the way the FAS...

Re: intermittent FF wind field with TurbSim

Your TIMESR input is rotated 180 from the mean wind direction. The mean u component should almost always be positive, but you've defined them to all be negative in your input file. TurbSim's output is actually equivalent to your input file, though. It uses the convenction that u is positive in the m...

Re: intermittent FF wind field with TurbSim

Anup,

Is the wind direction at the hub 0 degrees? You should be able to see this in the TurbSim summary file.

If it is 0, I would not expect any difference in the wind time series output, including the sign.

Re: Sending RtAeroPwr via ServoDyn to Bladed-Style DLL Controller

Hi, Paul. I don't see anything in your code that would be problematic. I suspect that the code isn't linking with the new compiled version of the FAST_types.f90 files, which is what causes the access violations. (I have had this problem before, myself.

Re: Instructions for Compiling FAST

Juan, You need to tell the compiler to preprocess the source file. With gfortran, you add the "-cpp" option to the build command that you used (on Intel Fortran, you use '-fpp'): gfortran -cpp -c -fPIC DISCONChanges.f90 In these particular source files, though, the preprocessor directives ...

Re: intermittent FF wind field with TurbSim

Hi Anup, You should get exactly the same time series output at the single point that you input; I would assume that you set that point to be at the hub. If you are not getting that output, check the time-series input file to make sure your measurement point is exactly on a grid point and that it's r...

Re: nComp=2 in TurbSim

Hi, Jan. I think this bug has been fixed in the latest version of OpenFAST (https://github.com/openfast/openfast). It might be in the master branch, but I'm pretty certain it was merged into the dev branch. Let me know if that doesn't fix the problem. When you set nComp to 2, though, it just sets w ...

Re: FAST v8.16.00 on MAC OS v10.12.6

That should be the only line you have to change. Your $(BIN_DIR) is set to ../bin at the top of that makefile, so I would set MAP_lib = /usr/lib/libmap-1.20.10.dylib or if you changed it to have a .so extension, you would use MAP_lib = /usr/lib/libmap-1.20.10.so I don't think the file extension that...

Re: Wind profile in a stable atmosphere

Hi, Astrid. There is a single stability parameter, RICH_NO, for each TurbSim simulation. Stability could, of course, vary with height, but that was not what was implemented in the code. You'd have to ask Neil Kelley, who originally pulled together the theory for TurbSim (and its predecessor codes), ...

Re: Instructions for Compiling FAST

Zahir, The first errors about InflowWind's UniformWind submodule might be due to something wrong in the auto-generated IfW_UniformWind_Types.f90 file. If you add a space in the IfW_UniformWind.txt file, it should regenerate that file. (If that doesn't work, you could probably grab this file , but I'...
