* This test case has simple geometry and boundary conditions, involving transient, isothermal, incompressible laminar flow in a three-dimensional box domain.

|
* It is intended to stress test the linear algebra solver, most of the time being spent in the pressure equation.

In this simple geometry, all the boundaries of the box are walls. The top wall moves in the x-direction at the speed of 1 m/s while the other five are stationary. Three different sizes have been selected:
