Fluent periodicity problem

CFD_boy

Hi,I'm doing a simulation on a turbine rotor and i have a classical periodicity problem: i set the the rotational periodic type in boundary conditions; the turbine have 25 blades and so when i check the grid, messages correctly say that the angle is 14.400 degree. When i run the simulation results aren't periodic in static pressure and temperature on the inlet surface (the outlet is ok). I can't found the reason, i think that maybe gambit generate a wrong grid but when i make the check i get no error messages. Does anybody have a suggestion for me? Thanks in advantage.
