Default Moving boundary in fluent!

Dear all,

I have a rectangular (solid) geometry with a small semicircle at the bottom...Now the bottom boundary changes with time and the shape of the semicircles changes slowly to a parabola kind of shape say and the process continues till it touches the top boundary....I want to find its final shape.

Any idea of how this can be simulated? If this is taken as change in geometry every second it would be very painful i guess....Though i think one can take the rectangular geometry to be constant(overall) and the semicircle/parabola part is filled with gas/air...Please let me know if this is possible!!

Thanks a lot!!
