Water turbine simulation result did not converge

Hi,

 

Some background  about the problem;

 

I have build a model of water turbine with rotating part (1000 rpm)  and I need to extract few results from the simulation such as Mass Flow Rate, Total Pressure, Efficiency. I have manage to set the rotating region and set few surface goals to extract the required goals.

 

Problem;

 

The simulation running well until 1500 iterations and after that, all goals that I set up earlier begin to oscillate and did not converge even after 20000 iterations. However the Mass Flow Rate did not oscillate and converge.

 

So I was hoping if there are anyone in here has experience with this problem help me to solve them.

 

Cheers.
