Pressure tank simulation
 
Does anyone das experience with pressure tank simulation? Problem is that it is closed area with no outlet and inlet. There is time dependable temperature boundary condition on the boundary of the tank. That means that encreasing temperature should encrease pressure inside the tank. Initial pressure of the fluid is 15 MPa. I tried to use time dependable model in Fluent 4.5 but it wrote me something like: "mass imbalance using outlet" while calculating.

Use "density function of pressure", mass flux inlet and "Floating operating pressure"
