I'm simulating a turbine.
The convergence of solution is monitored by checking the residuals of the numerically solved governing equations. The "viscous-spalarat-almaras" model is used, and used air with constant density. Pressure-velocity coupled scheme and pressure based solver are selected.
According to the following figures, torque is increasing but the residual of continuity does not decrease and is almost constant. T

Is there any problem?
According to monitored torque, the solution is not converged.
