Hi @Sam-Ramsahoye I took a quick look at version 3.2, and I think the issue is not with `WaveMod = 6` itself. It looks like the wave kinematics are read...

@Sam-Ramsahoye OpenFAST does not compute the buoyancy load using displaced volume. Instead, the hydrostatic load (a more accurate term than buoyancy in this case) is obtained by integrating the constant...

@Sam-Ramsahoye I've attached below an example wave-component input file for `WaveMod`=7. To run it with SeaState, set the following in the `WAVES` section of the SeaState input file: 1. `WaveMod`...

Hi @jjonkman, @RBergua and I have investigated this a little bit more. More specifically, we are looking into why the Guyan modes for a floating structure including pre-tensioned cables can...

@andrew-platt I updated the MoorDyn and HydroDyn c-binding by replacing the calls to SmllRotTrans with EulerConstructZYX. I hope this is all we needed to do. It is the user's responsibility...

I believe the observed behavior is a consequence of how SubDyn applies self-weight to the structure. During initialization, the force and moment due to the self-weight of each element are...

Hi @deslaughter, I added a new SD driver r-test here https://github.com/OpenFAST/r-test/pull/156. This provides an example where we have multiple transition pieces and rigid-body DoF tracked by SD. We can update...

Hi @jjonkman, the "A" matrix is different on Linux. For instance, on Linux, the "A" matrix in the .lin file has all expected entries even if `gravity` and `AddF0(3)` are...
