Default How to get coincident mesh at interface

Dear Foamers,

I used snappyHexMesh and different stl files to create my mesh, following the mixerVesselAMI tutoriel.

My problem is that at the internal face between the rotor and stator zones, the mesh is non coincident.
Below is a picture of the mesh, showing this non-coincidence.

I know for AMI computation it is not a problem. However, I want to run a MRF steady computation, without specifying AMIcyclic conditon at the interface.

So my question is, is there a way to make such a mesh coincident at the internal face ? Is it an option in snappyHexMeshDict ?

I tried to use stitchMesh, once my mesh was created, without success. Is there any other possibility ?

Thank you in advance for your help,
