I am new to model DEM using ANSYS Fluent.

I started with a simple model - a cylinder is filled full with a fluid (density is 1963kg/m^3), the particles (density is 1750kg/m^3) are injected from the bottom of the cylinder.

I expected to see the particles are rising due to buoyancy forces. However, the particles are stick together, I didn't see the affect of buoyancy forces.

Please advise.

Thanks,

the first question to find out is: is buoyancy included in the model?
