Hi All,

Anybody know how I can define a wall in which only vapor can pass through it after evaporated close to the wall?
My domain is the follows:

a box with a wall inside. The wall separates two different regions, one with atmospheric pressure, the other one with vacuum. Water enters the box in the region with atmospheric pressure and, close to the wall, starts to evaporate. But the wall is hydrophobic, so, only the vapor, due to the pressure difference, pass through the wall.

Any suggestion?

Thanks
