Help me? (EOS3) simulate a two-phase test.

Hi,everyone
Right now, i want to simulate water drainage experiment, as first conducted by Liakopoulos(Liakopoulos, A.C., 1965. Transient Flow Through
Unsaturated Porous Media.Ph.D. Dissertation. University of California, Berkeley.) The column in this experiment had a height of 1.0 m, was packed
with Del Monte sand, and was instrumented to measure the moisture tension at different points along the column. Before the experiment, water was
added continuously from the top and was allowed to flow freely at the bottom of the column through a filter until uniform flow conditions were
established. Then, the water inflow at the top of the column was ceased and the tension meter readings were recorded for 120 min.
I have got the initial conditions, as shown in INCON, then i simulate 120 min,but no change to water saturation, it means there is no water outflow at the bottom of the model, actually water should be discharged under gravity, can anybody fix it for me? thans very much!
The initial condition get from input1, then run a simulation of the two-phase test with input2

I'm sorry to bother
