Hi all,

I am currently modeling a turbine using periodic functions so my domain is one stator/rotor/stator arrangement. Having used mixing planes for steady calculations i now am running unsteady calculations and from what i have researched i need to apply a mixing plane for this. My problem is the periodicity of each zone must be the same, however i have 26 stators (on each set upstream and downstream of rotor) and 30 rotor blades so it is not. I do not have the computational power to model the full wheel so need to scale the stator zones somehow. Do i just scale dimensions in the radial plane and leave height as is or how do i do it? Do i need to scale inputs or results from the zone? Or is there an easier way? Previously i have modeled unsteady flow on this problem using mixing plane but it only works uni-directionally and not bi-directionally (as is the nature of this flow).

Thanks in advance for any help.
