  I am trying to do a two-phase boiling simulation in fluent in a rectangular channel. I have given constant mass flux inlet as inlet BC and gauge zero pressure as the outlet BC. But during the transient simulation run, I found my outlet pressure varies with time, but it should be constant as i have given in the BC

  Please post what you're monitoring, and what you set. "Pressure" has several options, so Total, Static etc.

  Please find the screenshots below in which ihave mentioned how i have created the report definition for p_in, p_out and del_P

  And the outlet condition you set? How much variation are you seeing?

  The outlet condition given in screen shots along with plot for p_out-blue . The p_out max value is around 4000 Pa. In the simualtion upto time 0.005 s it is for single phase beyond that its two phase.
