EDEM for electrostatic field

miaomi

Hi,

In the EDEM and Fluent coupling, I want to simulate particle agglomeration due to electrostatic forces. Should the electrostatic field be set in Fluent or EDEM?

Which software should the electrostatic force field be obtained from?

Hi,

By default EDEM doesn't have any built-in physics models that interact with electrostatic fields. The fluent coupling allows for 2-way drag forces and species transfer but no electrostatic force coupling.

There is an electrostatics module in EDEM:

But this doesn't read in a field information, it takes the electrostatic charge of a particle.

You can import a field and write your own physics model as to how the particles interact with it. A starting point for that would be:

Thank you, I will try it
