I ran Fluent-Rocky 2-way coupling with Eulerian multiphase in Fluent, particle phase volume fraction is always 0. But i can see particle is moving into fluid in Rocky, which means particle volume fraction should be non-zero because of particle. How can i get particle phase volume fraction?

Check how the coupling is set up as Rocky may be passing the volume fraction back as a flow resistance and you should be looking in the UDMs for volume fraction.

Thank you for your reply. I found that because ROCKY will copy FLUENT CAS FILE to their own folder and save data there, and need some work to find.

Embbed coupling by Rocky have no UDM to use.
