(porous)interFoam: Pressure in trapped air

Hi Foamers,
I'm trying to simulate the filling of a cavity, which is a porous zone. This cavity is initially filled with air. In the middle of the cavity, there is an obstacle, that creates an air trap. Now, as I defined a pressure of 0 Pa on the outlet, which persists in the air filled zone, I would expect the trap to be filled up with liquid. At least, this is what Pam-RTM simulates and what happens in experiment. But, after the air is trapped, its pressure increases suddenly and stops the flow from advancing. Why does that happen? I attached a sketch and my case (to be run blockMesh and porousInterFoam). Thank you, Kind Regards Peter Last edited by John Degenkolb; October 15, 2014 at 08:35.
