Contour Problem in Interface Boundary
 

Hello Fluent User,

I am simulating 2-phase solid-liquid flow in mixing tank using Mixture model, sliding mesh, transient. My study focused the concentration of solids within the tank and Macro Instabilities.

My mesh area is divided by a circular interface boundary between static fluid zone and moving fluid zone.

The problem is, i can't get a smooth contour between the zone near the interface boundary. There always a "crack" or broken contour that not continuing the contour from each other zone. Seems like, each zone have their own contour and not interacting with other zone.

Below are the images of my simulation:
