Hello,

I am trying to simulate a GAS-solid fluid in an Eulerian-Lagrangian framework, only using FLUENT.
There is about one pipe which a derivation (SEE IMAGE):
For one side, the air is introduced, and for the derivation, the particles are presented. In the outlet, there is a mixture between air and gas.
However, I am not sure if it is correct to introduce the particles with the injection option? (Discrete phase>Injections)
Or should I'd work with the Multiphase option?

Thanks.
