I simulate the attached system, using the two phase fluid and the self crated properties block with the properties of hydrogen. The tank has 7 bar, the reservoir has 2 bar. Imidiatelly after starting simulation, the pressure in the tank drops down to the level of the reservoir (2 bar). That makes logical for me so sence. When I have a pressure tank with a small exit (area: 1e-4 m²) the pressure in the tank should go down slowly. The level is also plottet, where one can see that even the tank goes empty slowly.

So waht could be my mistake here?I simulate the attached system, using the two phase fluid and the self crated properties block with the properties of hydrogen.
