This is an example of a transient situation.
Consider the unit square [0,1]x[0,1] with a jet aperture centered in (0, 0.5) and 1/16 wide.
The jet profile is parabolic with maximum velocity of one.
The problem is solved using a uniform mesh of 16x16 Q2Q1 elements.
Figures below show streamlines and pressure profiles at different instants.
