My simulation keeps crashing when the hull is pitching and lifts out of the water as speed increases, I guess it has to do with the mesh alignment(?).

As could be seen in the highlighted areas there is a mismatch in the overlapping of the cells. The overset mesh is lagging somewhat behind leaving an undefined area just ahead of it, before the transition/connection to the background domain.

I'm a rookie on overset meshes, but could it be something wrong with the hole cutting?

...........fixed:

- too many changes from sim to sim.
- just had to refine the VOF mesh at the bow (was just testing stuff, wanted as short comp. time as possible)
