mesh interface
 

I want to connect two fluid areas with a mesh interface. if I want to connect 360° faces, I have two options

1. Create a mesh interface using the "frozen roter method".
(Domain → Turbomachinery → Turbo Create)
2. Create a mesh interface by selecting the two surfaces to be connected from the mesh interface in FLUENT.
(Domain → Mesh Interfaces)

Does either method do the same thing?
