Yes, it would be nice. It is not straightfoward though: even for a single rigid body, the translation and rotation dofs have different units in the equation of motion. In...

A quick update: 1. [There is a new feature in xarray to better support units](https://xarray.dev/blog/introducing-pint-xarray) 2. It might be possible to define the ampitude of motion of translation and rotation...

Whenever we can do a big breaking change, we should maybe replace `free_surface` and `sea_bottom` in the `RadiationProblem` and `DiffractionProblem` by a single `water_depth` parameter. And create a new kind...

Interesting, I don"t remember ever having this problem. Could you give some details on the problem you are working on? You can try a direct solver with the following syntax:...

There seems to be overlapping panels where the cylinders meet. It might be the issue. What if you add some vertical space between the cylinders ?

> Now I will immediately fix this error in BEMRosetta. The mistake is on my side: the wave direction should be in degrees in Nemoh.cal for consistency with Nemoh. It...

A late follow-up on this topic: I can reproduce the GMRES convergence issue for omega ~ 1.4. When using a direct linear solver, there is no convergence issue, but the...

Thank you very much. I don't have time to look at it in details right now, but I will. Just a quick comment: the `wave_direction` argument takes an angle in...

It is also a problem for the archive on Zenodo, since it is pulled automatically from Github.

The paper implies that the inacurracy of Nemoh could be due to the use of a tabulation of the Green function. However, when disabling the tabulation in Capytaine (at the...
