I'm running a compressible realizableKE model on a 90 degree slice of an injector geometry. For some reason, I have a factor of 2 jump in epsilon across the cyclic patch, and also a smaller jump in k. Has anyone encountered a similar problem? My boundary conditions are cyclic across patch, with zeroGradient at walls and fixed value at inlet for both k and for epsilon.
