good day to everyone. I am having a problem with my solution as attached in the picture. First, I applied shared topology in my geometry in both interfaces (rotor-inlet,rotor-outlet) using spaceclaim and at the same time i also created named selection on the interface of inlet (connects to the rotor), interfaces of the rotor (one that connects to the inlet and one that connects to the outlet) and the another interface im the outlet (connects to the rotor). During the meshing process I actually assigned these interfaces to a symmetry boundary condition then in the solution, I changed the type of these symmetry to an interface, however, the "warning: unassigned interface zone detected for interface.." popped up. So, I assigned them as symmetry as the original setup and  I tried to initialize and run some calculations but "reverse flow on the faces...at the inlet amd outlet domain" keeps on popping up in the console and data plots of my desired output barely changes in their values. Alternatively, I deleted the named selections of all interfaces in spaceclaim since I already applied shared topology and tried to mesh it in fluent but all the interfaces inflated, it was like the interfaces were assigned automatically as walls in the ansys fluent meshing. What else can I do to ensure flow is initialized across my domains? Thank you in advance for your help.

Hi

I suggest you to try creating mesh interface using Domain > Interfaces > Mesh. Then select the boundaries making up the interfaces and click Create. Then you can initialize your solution.

Hi. Thank you for your reply. I tried to make the symmetry as a wall boundary type in the ansys solution then tried to slit these face zones thru the console. Then I classified these zones into interfaces. After that, I manually created mesh interfaces. I already solved my problem.
