I am having trouble applying periodic boundary conditions to my 3D problem in Workbench.

I have modelled and meshed one stator on the hub and I want this to have periodic boundary conditions on each side in order to characterise the flow.

Does the geometry on each side of the mesh, the periodic interfaces, need to be identicle as I think this may be my problem? can anyone provide a step by step guide on how to apply this periodic/cyclic BC's.

I managed to do this 2D with use of TUI, define>mesh-interfaces/make-periodic, having defined the two edges as interfaces in the mesher component of Workbench. The 3D geometry is a bit more problematic.

Thanks.

Just trying to bump the thread up in hope of a reply

I am modelling a similar problem (stator (nozzle)blade of 1 Stage of a Low Pressure Turbine) however I am unable to figure out what should be the boundary conditions for my problem as I do not have anything before nozzles (no rotors). My geometry model as obtained from Tgrid looks like:



My doubt is that if I should be using identical domain geometry on pressure and suction side of the turbine. As, this domain has been automatically created by TGrid and I am not sure if it is correct.

Also, Can anyone help me in setting up periodic Boundary Conditions for this problem.

Thanks in Advance.
