I'm trying to model mixing tank. Now, I can predict the mass transfer coefficient. I also try to predict the dissolved oxygen concentration. I specify the dissolved oxygen as an additional variable but i don't know how to add source term. I try many cases. All case give the linear solver error even if i reduce the time step.
Please give me an example for predict the dissolved oxygen.
Many thanks for your help

I strongly doubt you will find any tutorials, your application is pretty specialised. Feel free to ask CFX support, they may have some thing applicable.
Have you used any source term linearisation? This can greatly improve convergence in some situations. Read the documentation on source term linearisation.
