Hi Everybody

i am new to this forum, i have problem in simulating a simple gravity flow case. i have a tank of 900 mm dia and 1100 mm height containing water which is draining through 11 mm hole at the bottom. both inlet and outlet are exposed to the atmosphere. I am using fluent with pressure conditions at the inlet and the outlet and gravity contions are on. i cannot get any solution if i give zero gauge pressures, however if i increase the pressure values ( both same at inlet and outlet) i cannot get any flow out of the domain. Can any one help me in this regard, it is just the draing of tank under gravity,

thanks in advance
