Dear,
I am performing a rotor and diffuser simulation of a centrifugal pump, I created the blades of the two geometries through the BLADE GEN, creating the independent meshes with the MESH. In the setup of CFX I realized that in the interface the elements of the meshes are not coincident, I did in the setup of the interface STAGE and FROZEN ROTOR and the connection is GGI, I'm not sure that the mass transfer in this region is correct because the elements are not coincident, Is there any command to do this fix? I think in this interface an interpolation is performed, but, I'm not sure.

if you want matching elements on the interface there are 2 ways of doing that.

-1- in design modeler form a multibody part (mesh by default will than be equal on both sides of the interface) Personaly I always use this one.

-2- use mesh conection features inside mesher
