Good day, I been search for how to switch on two way coupling between discrete and continuous phase? It is turn on the two way turbulence coupling in physical model ?

Option to select two-way coupling is available under Discrete Phase Model

Thank CFD.Engineer007.

I wanna know is that any different if
1. I run steady simulation until the solution converge then run the simulation with transient simulation.
2. I straight run the simulation in transient state.

The result will it be huge different with above two method?

In both cases you will end up with different flow fields, and hence your particle trajectories will be different. When you select two way coupling, a source term is passed onto the momentum equations that changes the flow field after every n iterations

Thanks sir, I understand it already.
