@skpal-1 I agree that it's strange that it worked in `Debug` but not `Release`. Generally debugging won't work in `Release` mode anyway because the executable doesn't include the necessary symbols...

Yes, you will need to install BLAS/LAPACK separately. How did you install gfortran? If you used `mingw` then you can download the Windows binaries of OpenBLAS from https://github.com/OpenMathLib/OpenBLAS/releases and unzip...

The quick fix for the `FAST.sln` compilation is to change line 258 of `vs-build/RunRegistry.bat` from `%REGISTRY% "%CURR_LOC%\%ModuleName%_Registry.txt" -I "%NWTC_Lib_Loc%" -O "%Output_Loc%"` to `%REGISTRY% "%CURR_LOC%\%ModuleName%_Registry.txt" -I "%NWTC_Lib_Loc%" -I "%SEAST_Loc%" -O "%Output_Loc%"`...

@kyy2233 I'm not entirely sure how to make this work, but I can offer some suggestions. First, are you running these simulations on Windows? And did you build the Mex...

@jjonkman The last time that I did performance profiling, the majority of the computation was in building the solver Jacobian, not solving for state and input updates. Though, with 20...

@RBergua Thanks for providing the model, it was helpful to run the profile and see where the time was being spent. I agree that the solver Jacobian is only being...

@RBergua I was able to take `ConvTol` up to 7e-2 which resulted in 2 convergence iterations and a time that seemed comparable to OpenFAST v4.1.1 (~1600 seconds on my laptop)....

@RBergua I think if you're going to use MoorDyn as part of the structural solve, then you're going to need it as one of the tight-coupling modules or you'll need...

@Jamie7963 There's something strange going on with the paths in the commands that CMake is executing. It looks like they haven't been quoted because it thinks the path to the...
