No particle movement take place, solid are remain at rest in EDEM -Fluent coupling in fluidized bed

PhD scholar Mahesh

In EDEM-Fluent coupled simulation, I used the same boundary conditions as the tutorial on the fluidized bed, but I used a different geometry, so particle movement occurred but solids remained at rest.

Hi,

With your new geometry/mesh, are you sure your particles are still smaller in volume than the mesh cells ? Having particle volumes larger than the cell volumes is probably the most common numerical issue.

Failing that, are you sure the length scales are the same? Check the domains in both EDEM and Fluent to make sure they match up.

yes, in both EDEM and Fluent the mesh size is greater than particle size.

Both EDEM and Fluent have the same dimensions

Ok, that's good.

When you say:

"so particle movement occurred but solids remained at rest."

what do you mean when you say solids?

Also, are forces being transferred between EDEM and Fluent? You can tell this by looking at the 'Coupling force' in EDEM.
