step to get convergent cfd
 

I have read in article that to steps to get convergent are:
(a) With initial boundary conditions, compute the flow for gas phase without particles until a convergent result is obtained.
(b) Based on the calculation results from step (a), compute the flow for the solid phase until a converged solution occurs.
(c) Based on steps (a) and (b), conduct the calculation for gas and solid phase.
(d) Repeat step (a), (b) and (c) until convergent solutions occur for both of gas phase and solid phase.

the model is multiphase,transit, gas-solid
could anyone please explain to me how i can implement the above steps in fluent ?

This forum is for Converge questions. I think you will have more luck with your inquiry in the ANSYS Fluent section.
