How to define the size of particle in Eulerian
 
Hi,
I simulate the particle behavior in a room. I want to use Eulerian multiphase to simulate the particles. But, I do not know how to define/cahnge the particle size.
Anyone knows?

I assume, you specified your dispersed phase as particle phase? So you can enter the diameter of the particles in the "Multiphase Interaction" node in the physics continuum.

Please note, this diameter will not be taken into account for the drag force. To model the drag force, you need to specify the drag coefficient. This might be confusing, but that's because the particles don't need to be spheres, therefore the drag law might be entered according to the expected behaviour.
