[ICEM] errors in defining periodic boundary conditions

ahirekar10 · April 30, 2014, 14:14

Hi friends,
I am meshing 20 degree sector combustor geometry in ICEM CFD. I want to get the periodic faces so I tried to apply rotational boundary condition by defining axis and giving the required angle. But when the mesh is ready and I am checking for the probable errors I am getting message that no periodicity has been applied why this is happening??
I did like this Global mesh set up>>periodicity>>rotational periodic
Why am I getting this erro please help
Thank you in advance

Periodic mesh works just with Octree algorithm.
Create surface mesh with Octree and after that 3D mesh with Delaunay.
