Thank you for the help.

First, as you can see I use water in the cell zone panel.

 

Then, thank you for the link, I understood the plotted pressure doesn't contains the hydrostatic term. But in that case I have two questions :

  • Even if it is very low I have still a hydrostatic pressure profile, and it is too clear to be a machine zero error. And multiplying the gravity by 10^13 I obtain the right hydrostatic profile. Why ?
  • Why is the velocity so low ? you see I have water but even with air it should be greater.
