You need to tell it to build a shared library, otherwise it thinks it is a standalone executable that needs a main() routine. Try gfortran DISCON.F90 -shared -DIMPLICIT_DLLEXPORT -o DISCON.dll (Or maybe you want a different file extension for linux?) Alternatively, the DLLs can be built using cmake....

Is it possible that you are reading the Z component backwards from the .u file? The text files are written with Z this direction: Y(1) Y(2) … Y(nY) |---------------------------- Z(nZ) | Z(nZ-1) | … | Z(1) | I'd recommend applying the time shift to your own files, and comparing time histories at diff...

Your screenshot shows that it is looking for the ElastoDyn blade file in the IEA-15_240-RWT directory, but it appears that it is not where it is located. You should open the primary ElastoDyn input file and change the location where it can find the IEA-15_240-RWT_ElastoDyn_blade.dat file. (and note ...

I don't know how you have defined your nodes, but if you are matching at the hub node and NOT matching as you move out radially from the hub, I would suspect that there is an error in one or more of the position calculations. Perhaps you can calculate the equivalent shift on your plot by matching th...

Riccardo, A few comments: 1. Some older versions of FAST/InflowWind did interpolation differently than the current version. It now does a tri-linear interpolation. 2. When InflowWind reads the FF grid files, it shifts them so that at time zero, the wind field starts half the grid width in front of t...

Does your FAST7 file contain a variable called "AeroFile"? It's possible your FAST7 model calls it something else (possibly "ADFile"). If you don't have "AeroFile", change the name of the variable in the input file that points to the file containing AeroDyn input parame...

It looks like you are missing a comment line in your HydroDyn input file. Please add the line for the table units as below: ---------------------- MEMBER OUTPUT LIST -------------------------------------- 0 NMOutputs - Number of member outputs (-) [must be < 10] MemberID NOutLoc NodeLocs [NOutLoc < ...

1. This issue should be fixed in the "dev" branch of OpenFAST. If you need to use the master branch, you can update the FAST solution file to solve this issue by following the instructions in this GitHub issue: https://github.com/OpenFAST/openfast/issues/509 2. I would guess that the path ...

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.

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...

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...

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...

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 ...

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...

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...
