Below are the boundary conditions I set for this simulation:nVelocity inlet: velocity magnitude 0.001 m/s normal to boundary, temperature 300KnPressure Outlet: gauge pressure 0 PanWall: stationary wall, no-slip condition, temperature 543KnI get this pressure distribution but I expect a pressure change to occur at the nozzle tip (the section where there is a dimensional change).nI then tried to specify the initial gauge pressure of 1.64e6 Pa at the velocity inlet boundary condition window but I still get the same result.
