[FAQ]

The hydrostatic (gravity) contribution does not appear in the static pressure display. This is due to the definition of pressure in the momentum equations: You can include hydrostatic pressure by explicitly setting the operating density and reference density as follows. Assuming a fluid density of 1000, 1) Activate the Specified Operating Density option and set the operating density to zero. (TUI: define/operating-conditions/specified operating density = 0.0) 2) Set the reference density equal to the fluid density (TUI: report/reference values/density = fluid density (1000) 3) Reconverge the solution (TUI: solve/iterate) 4) Plot the pressure contours
