Hello everythone,
I meet a problems about cyclicAMI for it is required to have the same topology or geometry betwwen two meshes.But in reality,the interface of impeller is smaller than the face of volute as you can see the photos below.And then I turn to the SpaceClaim which is a 3D model designer,but it's still difficult to project the lines to the another face.
At Here, I want to know whether it is a prefect way to solve this kind of interface matching problem.

IMG of Volute :

I will appeciate it if you can give me a hand!
BTW:in the attachment,thers are some files,including the four GEOs which I used.

You should really make them fit top to bottom to get a good interface.

It does not matter that the physical height doesn't match, just that the interface does.

I opened in Salome and the circumferential lines are matching just fine

Just a small heads-up.


Your faces just near the tongue are poorly defined and difficult to mesh.

Thank you,linneman!
Is it possible to create a boundary type that makes it like the Inferface in commerical codes? By now, I need to go to the 3D pre-processing software to make the circumferential lines projected to the volute so that I can give a name-selection of this face in the volute.
When it's required to do some batch processing, we need to specify every geometry by using that way.
Best Wishes!
