Hello,
I am trying to create a 3D geometry to study a high speed impact of a plate against water.

My actual geometry is divided into 3 parts. The fluid domain, the moving fluid and the influence part. The fluid domain would be the tank, the moving fluid would be a spherical part of the domain that moves with the plate with fixed mesh inside (finer one) and the influence part is the smaller rectangular prism created to mesh using the body of influence option. The plate is a hole in the domain.

I attach a picture of the geometry below.

The meshing would be made with a refinement around the plate and using the body of influence option as well.

My problem is that I find that there are several "connection" appearing and when I start fluent it seems to introduce a lot more boundaries like walls.

*UPDATE*: I have realised that the moving fluid domain (sphere) and the fluid domain do not actually share boundary when meshing and that may be the reason why I have additional boundaries as walls. I don't know how to fix it since in the geometry they share that boundary.

*UPDATE #2*: I solved the problem by introducing both domains in the same component in spaceclaim and selecting shared topology.

Thank you in advance.
