Flow come out of environment pressure?

Hello,
I am trying to pass .1928 kg/s at 5 bar of steam through this tube and expand to 5 bar and decrease to 400 K. I have placed the inlet mass flow rate on the left and environment pressure at the right. My problem is that when I run the simulation and insert flow trajectories, the flow comes enters from the environment pressure and stays at constant temperature at whatever I set the envrionment pressure. So if I set the environment pressure to 600k, the temperature in the tube stays at 600 k regardless off what I have at the inlet. Why is the flow coming out of the environment pressure instead of the inlet and why won't my temperature start at my inlet temperature of 952 K?test.JPG
