interFoam pressure conservation
 
Hi All,
I am trying to run some free surface cases using interFoam where I have 1 atm of pressure in the air and 2 atm of pressure in the water. The geometry is small enough such that the pressure difference should be accounted for by the surface tension of the water.

At present I am setting the two pressures in the initial conditions, however after the first timestep, the patched pressure has disappeard and all i have is the hydrostatic pressure from the water.

Am I missing something or is interFoam not capable of dealing with a discontinuous pressure.

Thanks

Andrew
