Hello guys, I am learing how to use the overset mesh with DFBI, for using them in a project for my thesis. Following the tutorial with the Lifeboat I tried to set-up a sphere just floating. The solution converges in the correct draft for the sphere's weight however I have this discontinuity in the free surface. I have given caution in the following points:

- Same mesh size in the overset and background mesh
- Interface was generated
- Overset Mesh boundary condition was selected for all surfaces of the overset block except from the symmetry

Thank you very much for your time.

Hi, may I know did you solve this issue as I faced the same problem now. Thank you very much.
