flow calculation in rotating blade passages
 
for a rotational speed greater than zero and when a) inlet boundary conditions are total temperature and pressure, in addition to flow direcition; b) outlet boundary conditions are static pressure; c) initial condition is set to a constant value; then the direction of the flow after a number of iterations is reverse and then diverges. Are there any hints to start the calculations and get converged solution? Thank you.

R u sure that the code is ok? and the outlet static pressure is right?

if yes. Plz change lower the outlet static pressure to get convergence. and then use that as new computations' intial flow field.
