Dear OF-users,
I just uploaded on my channel a video of a computation done with a surface piercing propeller.

Thanks for sharing this video Stéphane,

Would you be able to give us details on the solver and numerical schemes you used ?

-Louis

Hi Louis,

Sorry for the very late answer. I saw your post only today!

Find attached the fvSolution and FvSchemes files. The files are the ones of the mixerVesselAMI tuorial. I used the interDyMFoam solver.

From my point of view, very often, problems come from the mesh, especially at the interface between the rotating and static parts. It is better to have coarse cells (same size on both sides).

Firstly I ran the tutorial case with my propeller geometry. I used the same standard settings, only the geometry was different (and snappyHexMeshDict file).

Then I took the controlDict, fvSchemes and fvSolution files of the mixerVesselAMI tuorial and reran successfully the case.

Regards,
Stéphane.
