rotational periodic boundary conditions in ICEM
 
How do I set rotationally periodic BCs in ICEM tetra?

I set Global Mesh Parameters>Periodicity>Rotational Periodicity, base (0 0 0), axis of rotation (0 0 1) z-plane, and angle 45.

I have a 45 degree pi slice of a disk. Then I generated a tetra volume mesh automatically from ICEM.

Then I set the BC of the periodic faces to periodic in the Output>Boundary Conditions.

I output the mesh and read it into fluent, and get the error:

Warning: Innapropriate zone type (periodic) for one-sided face zone, Changing to wall.

The periodic faces are different parts. I tried setting the periodic faces to the same part but get the same error.

Any suggestions?

Thanks!

Periodic mesh works just with Octree algorithm.
Use Octree to create (Lock) surf mesh for other volume algorithms.
