Hello,
Can someone help me please?

I use the electric and magnetic model in a fluid.
I apply a current density on one side and a zero potential as the other boundary conditions. It works well when the fluid is monophasic.

But when my fluid contains two phases, I can not impose a current density.
Why do I lose the ability to choose "flow in" when the domain is defined as a two-phase medium?

Is there a way to use this type of boundary condition in this case?
Has anyone tried this type of simulation?

Thanks a lot.
