Hello everybody,

I am working on overset meshes. This might be a very simple question but I didn't find an answer yet.

The simulation includes an object that directly touches a wall. Therefore I am using the zero gap interface.
I have the problem that at a certain time a whole is cut in the middle of the wall and the object.
What might be the issue here?

I have added a picture of the time step before the hole is cut and when it is cut.
It is a 3d simulation and the picture shows a sectional cut with yellow being the overset mesh and blue the background.

Thanks for any help
