Dear Users,

I am using the Ansys Fluent discrete phase model to define 2 discrete phases: one phase of bubbles and one phase consisting of solid particles. These phases are dispersed in a continuous liquid phase inside a big tank.

Now I would like to use different boundary conditions for the 2 discrete phases at the top boundary, namely I would like the bubbles to escape while the solid particles should stay inside the domain, but under 'boundary conditions' I can only apply the boundary behaviour for all DPM phases uniformly.

Does anybody know if this is possible? User-defined function perhaps?

Best regards,
Joshua
