Hello every one I am going to simulate transient problem. I want to know how can i calculate Pressure drop VS time on transient problem by using Fluent ? ( I have rectangular channel with transient problem of water flow with constant heat )

Go to surface monitor, from the Report type > select area- weighted average, from Field variable - static pressure and surfaces > select inlet. I assume you use pressure base solver with 0 pressure at the outlet, the the pressure drop will be In;et minus Outlet, which is essentially inlet pressure. Then, X-axis > select flow time and Get Data Every > select time step

Hi I am trying to do the same thing as far as calculating pressure drop vs time and am having trouble. Do you know if this is done the same way in Fluent 2019 R3? Also can this be done after a simulation is already run or does it need to be set up prior?
Thanks!
