Hello,



I have the geometry shown in the image. I'm supposed to simulate a fluidized bed reactor. I have divided my geometry into two parts. The red one is the freeboard where gas an solid particles interact, and the green one is to distribute the gas to the bed. However, while doing the simulation some particles of the bed seem to fall into the green zone. I don't know how to restrict the bed particles so they just interact in the red zone, I tried to use Fluid Cell Zones but it doesn't work for Eulerian model. I would really appreciate if someone could help me.



Thanks,



Daniela
