One fixed flow domain, subdivided into 1 by 1 cells Flow travels from left to right. The inlet velocity is 10 metres per second. The top and bottom walls have velocity zero. Each number is a horizontal velocity at the right-hand face of its cell. Velocity at wall = 0 m/s Velocity at wall = 0 m/s Inlet velocity= 10 m/s Outlet

Numbers: horizontal velocity (m/s) through each cell’s right-hand face.

Total flow: in 100% → out 100%

More cells let us describe more detail. These prescribed values illustrate conservation of mass; they are not a solved CFD flow field.
