Re: Changing TMax to 600s simulation time

One other comment: The wind file distributed with the sample test cases contains is only about 60 seconds long. We did this to keep the size of the archives a reasonable size. If you want to run a longer simulation, you'll have to use a different wind file.

Re: Compile Precomp

Those DLLs are necessary because you built with dynamic libraries instead of static ones. With dynamic libraries, you have a few options: ⋅ To run the code on the machine you compiled with, open the Intel compiler environment command window (this will be on your start menu, under something...

Re: Tendon failure in FAST modeling

The linking error you show is typically caused by a mismatch between libraries used to link the final executable. I don't recall the details of FAST8 builds, but make sure you are using consistent libraries and compile settings in all the files and projects. The first place I would check is under &q...

Re: Tendon failure in FAST modeling

I think if you remove the key word "ABSTRACT" from the specification of the three interface statements in OrcaFlexInterface.f90 (reported on lines 114, 127, and 145, the first 3 errors in your attachment), that will solve your issue. This was fixed in OpenFAST a while ago. Older Fortran co...

Re: binary .wnd specification

The basic summary file that InflowWind will read should be in this format: https://github.com/old-NWTC/InflowWind/blob/master/Docs/FORMAT_FF_Sum_File.pdf The values in the summary file are used to scale the values from the binary file back to dimensional velocities, so they should be the values you ...

Re: FAST8 Build Model problems

I don't have any experience building Simulink models for real-time simulation. I have read some comments about it in the MATLAB/Simulink documentation that I sent you. I do not think you have to modify the header file; I think you need to make sure MATLAB is setting the appropriate preprocessor flag...

Re: FAST8 Build Model problems

It looks like you've got multiple definitions of the header files that are needed for the build process. I am not sure why it would be looking for files in both the extern/include and rtw/c/src directories. Did you modify anything in the build process? Or any of the include paths? When you build usi...

Re: Interface Openfast in Simulink

The error you are showing indicates that the path to FAST_Library.h is not correct in the mex command. That said, the OpenFAST interface to Simulink has not worked after NREL moved from FAST8 to OpenFAST (the error messages in your attachment refer to this problem). I initiated a pull request to fix...

Re: MATLAB2HD script

Hi, Charlie. I am not exactly sure what the problem is, but the warning message indicates that it thinks there is a variable called "!" in the template that has a value of "20.0000 0.6300 0.6300 0 0 0 0 0 0 0 0 0 0". Perhaps it's not reading a table correctly? Do you get this pro...

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...
