Hi Eugenio,

Many thanks for the update. To clarify, did you suppress Outer Floater in Aqwa Workbench, or did you delete it in the geometry editor, i.e. in SpaceClaim/DesignModeler?

It should not make any difference whether the structure is fully submerged or not.

Please can you try adding a new hydrodynamic diffraction/response workflow, with the geometry linked from the previous workflow:

Then try running these fresh analyses to see whether the problem still occurs. It may be worth doing a test before you add in all of the cables etc.

Cheers, Mike
