Wall-driven flow in a semicircular cavity (Re=3000)
The upper wall is moving to the right with unit velocity. In the pictures the streamlines are plotted.

• The diameter D = 1
• The density = 1
• The Reynolds number Re = D/viscosity
• Velocity mesh: 17808 nodes, 35124 elements
• The time step = 0.0005
• Initial condition = rest state
• Number of time steps to reach the steady state = 123506
