The issue #854 appears **sometimes** when there is a rigid link connected to the interface joint AND there are cables involved. The model that I'm working with doesn't have any...

I do believe the problem is related to defining one beam at the interface joint and, at least, one rigid link to that same interface joint. For example: If I...

I'm using OpenFAST dev (commit 4fafe68) and I confirm that I can visualize the mooring lines from MoorDyn and the Morison elements from HydroDyn. Yay!  However, I'm facing a...

Dear @jjonkman, All the simulations have been performed with `GuyanLoadCorrection = True`. I'm not receiving any warning from SubDyn/OpenFAST. See below for reference:  I have also rerun the different...

Dear @jjonkman, The wrong Guyan modes look like rotational rigid body modes, but they have some inherent elastic contributions. For example, I have included one dummy rigid rigid link between...

Dear @jjonkman, It's hard to tell if the simple model with one universal joint would return the expected results. Note that if the Guyan modes are wrong, then the output...

I have been performing several tests for the USFLOWT design considering only one leg. All tests used the SubDyn stand-alone version. I apply one time-serie of vertical force to study...

Yes, @jjonkman. Our plan is to use the model with pretension and without geometric stiffness. Till now, we were using pretension = 0 N to effectively get rid off the...

For reference, the results from pyMAP (MAP++ in Python) are:  These results are quite aligned with the ones from MoorPy. But some significant differences can also be observed in...

After having a very interesting and useful conversation with @luwang00 about the analytical derivation of the cable elements considering geometrical stiffness, we can confirm that the stiffness matrix from MoorPy...
