Dynamic Mesh in Fluent

      Hi 

      I am simulating a single-tooth gear pump with an upstream and downstream flow in ANSYS Fluent. I uploaded my geometry here. The thickness of my geometry is 0.02mm. I want to move the face and side walls of the gear throw domain. At first, I used the moving wall, but I received an error message that the direction of the rotation was perpendicular to the rotational axis, so I decided to use a dynamic mesh. I don't have experience in dynamic mesh.I consider the outer walls of the domain to be periodic. I think if I rotate the walls of the gear, it will crash into the periodic walls and diverge the solution. Is there any way to solve my problem???

      Please sketch out the whole domain. The image above doesn't make much sense for a CFD model.

        Dear Rob. I updated the geometry. Actually, this is the domain that first came to my mind. As you see, its a single domain where I tried to move the gear faces, but I couldn't, and it came with an error.

      OK, the gear is spinning inside a single cavity? No inlets or outlets?
