Tank sloshing in Fluent: need help for initial condition
 

Hi everyone,
I am trying to simulate a sloshing tank problem using FLUENT(SEE THE IMAGE).However,I don't know how set the high pressure for gaseous phase in FLUENT software.Please help,thanks.[ATTACH]

At the time of initialization of the problem give a pressure say x.
That will give air a high pressure.
Or
you can give a pressure in operating conditions pannel
