Dear Foamers

I am trying to remove the water appears on the surface of grains in a domain. This domain is a pore scale model of a porous media. the water can be produced due to condensation or reaction. I want to remove this liquid water from the domain through one of boundaries (e.g. right).

What boundary conditions I should apply for interFoam at the outlet and also at the other boundaries?

I should mention that I used the following BCs and got illogical results:

Velocity: All patches except outlet and grains: zeroGradient
Outlet: pressureInletOutletVelocity
Grains: fixedValue=0

Pressure: All patches except outlet: zeroGradient
Outlet: fixedValue=0

alpha1: All patches except outlet: zeroGradient
Outlet: inletOutlet

Thanks for your helps in advance.

Regards,
Hossein
