Solution of the Navier-Stokes equations

The Navier-Stokes equations are the fundamental partial differentials equations that describe the flow of incompressible fluids. Finite element code FreeFem++ was used to compute 2D transient solution. The time interval over which the flow becomes stationary is presented in seconds.
