Dear All,

How are you all doing! I believe doing awesome!

I have a problem in understanding the convergence of my problems. I solve the model without cavitation and then with caviatation. I set my RMS residuals to 1e-06. I check for

1) Mass and Momentum to be below 1e-06
2) Turbulence to be below at least 1e-4
3) Volume fractions to be below 1e-4
4) Imbalance of all and most important is mass imbalance and P-volum imbalance almost near to zero
5) Flow - In - Mass boundary flow on in(viscor) and P-Mass boundary flow on in to that of Out - Mass boundary flow on Out (viscor) and P-Mass boundary flow on Out to be equal over the number of iterations.

Kindly let me know whether I am right or please correct me if I am wrong.

My Imbalance especially mass imbalance and P-volum imbalance oscillates at zero between 10 to 22 and I stop it at zero, when it has run long

Please some on solve me or suggest me the better way.

Best Regards
Akash A V
