I have a convergence problem with the continuity. Everything has converged easily except this. I use segregated ske model. DPM also exists.
I checked the fluxes of materials and difference of in/out is 0.1% compare to the total flow.
The residual is 2.44*10^-2. Is it cause by this small difference

hello
do have a real divergence on continuity, or you just think you have a problem because of the residual values?

To my mind, 10^-2 isn't so bad in free convection case for example...



do you plot some surfaces values during the computation? is the a stabilisation of these values?

Regards

Thank you very much for your answer.
The stabilization is good. I had some instability problem with epsilon but grid adaptation and lower urf solved it.
You are right, I also have free convection in my system, but not only free convection... Maybe it is caused by free convection.
The temperature surfaces show reasonably good results.
