My supersonic flow sim. doesn't converge, I need Help!!!

Hi, I am new using CFD... I'm using flow simulation solidworks, I got a problem trying to simulate the supersonic first stage of an axial flow compressor (rotor only).

This are my calculation of free vortex DCA blade:

GasAirideal
P1101.325Kpa
T1288K
T2-T15.50467833K
T2293.504678K
P2107.438473Kpa
N377RPM
FLOW397Sm3/s

I don't know why the iterations of the pressure go so high and never converge... I let you some print-screens to let figure out what's going on.

I will appreciate any help, comment or correction of whatever mistake that I have done.
