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...

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), ...

gfortran: error: ../bin/libmap-1.20.10.so: No such file or directory This error message indicates that it is looking for a file called ../bin/libmap-1.20.10.so ; however you seem to have named that file /usr/lib/libmap-1.20.10.dylib . You should be able to either copy your file to the location the ...

Ruiliang, I think this issue is related to https://github.com/OpenFAST/openfast/issues/152. You can get the error about not finding a label in {openfast}\vs-build\RunRegistry.bat if it does not contain Windows line endings. GitHub or git may have converted this file to use linux or mac line endings ...

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'...

Array bounds checking won't necessarily help with the Bladed-style DLL. The arrays between FAST/Bladed and the controller DLL pass an address, so the compiler isn't going to be able to provide bounds checking that way. The aeroelastic code that calls the Bladed DLL indicates how long the array is al...

Hi Xiaomin,

There should be a Visual Studio project in the FAST8 archive for compiling the FAST library. Please read the instructions in the FAST8 ReadMe (see page 54) for help in compiling with it.

Hi, Xioming. The pre-compiled FAST Library was really designed to be used with Simulink, which is why it is linking with Matlab libraries. If you aren't going to be using this in Matlab, you can compile with the SysIVF.f90 file instead of SysMatlab.f90 and then remove the Matlab libraries from the l...

Envision Energy modified the BeamDyn driver to allow multi-point loading. When our code for this was merged into the OpenFAST repository, we did not include documentation, which appears to be the cause of most of the confusion here. The multi-point loads are specified at the end of the APPLIED FORCE...

This looks like it is caused by a memory leak or not calling the FAST_End() routine at the end of the S function. The HydroDyn summary file probably gets closed in FAST_End(), so that's what I would look at first. How did you stop the simulation? FAST_End should be called with the S-function mdlTerm...

Hi, Luca.

Looks like you have a linking error, likely due to some path incorrect path.
I'd recommend cloning the OpenFAST repository on GitHub (https://github.com/OpenFAST/openfast) and using cmake. If you have questions about compiling it, you can post in the GitHub Issues page there.

TurbSim v2.0 uses v2.x of NWTC Library. I would not recommend using the Build.bat file for compilation; instead I would use the Visual Studio project file that should be part of the archive. Alternatively, NREL has recently added TurbSim to the OpenFAST repository on GitHub. You can fork/clone the h...

I don't have my notes on these models anymore, but the code documents the two values as follows: phiM = 1.0 + 4.7*zL ! Non-Dimensional Wind Shear phiE = (1.0 + 2.5*zL^0.6)^(3/2) where zL is a stability parameter based on RICH_NO : if (RICH_NO <= 0) zL = RICH_NO else if (RICH_NO <= 1/6) zL = RICH_NO ...

Hi, Luigia.

I added an x64 version to the TurbSim release, but have not tested it at all.

Hi, Luigia. I'm not sure why you got the subscript out of range error in the debugger. However, I compiled with the /fpe-all:0 option, which makes the compiler stop any time there is a IEEE numeric issue (underflow, overflow, NaN, Inf, etc.). It flagged a line in the Spec_API() routine, which I then...
