Hi everyone, I am trying to conduct simulations about cigarette smouldering combustion but having problems when defining packed bed. (The fuel material has been simplified to carbon-solid.)

I defined the zone as followings:

1. Use Eulerian Model and define the second phase as Granular -- Packed Bed;
2. Define the cell zone to porous zone (full zone);
3. Define the fuel zone (region) through "Path"

Unfortunately it didn't work...

It will be greatly appreciated if you have some ideas or suggestions about how to define this packed bed.

Thank you very much.
