How correctly take into account exhaust tube with 90-degree turn?

I am performing analysis of the existing axial subsonic compressor. I want take into account in my calculation exhaust tube with 90-degree turn.
My problem is that AxSTREAM incorrectly calculate flow parameters into the exhaust tube when i performing 2D analysis, because !!!! ENTROPY IS REDUCED INTO EXHAUST TUBE !!! ( when i performing 1D analysis everything's fine)

What am I doing wrong? Look please this screencast (use this link:
where i show my problem. In this vide you can see that when i do 1D analysis everything's fine, but when i do 2D analysis in the hub section ENTROPY IS REDUCED INTO EXHAUST TUBE.
