# Freeflow through a channel
-## Problem set-up
-This example contains a stationary free flow of a fluid through two parallel solid plates in two dimensions from left to right. The figure below shows the simulation set-up. The fluid flows into the system at the left with a constant velocity of $` v = 1~\frac{\text{m}}{\text{s}} `$. The inflow velocity profile is a block profile. Due to the no-slip, no-flow boundary conditions at the top and bottom plate, the velocity profile gradually assumes a parabolic shape along the channel. At the outlet, the pressure is fixed and a zero velocity gradient in x-direction is assumed. The physical domain, which is modeled is the rectangular domain $`x\in[0,10],~y\in[0,1]`$.
+You learn how to:
+* solve a free flow channel problem
+* set outflow boundary conditions in the free-flow context

+__Results:__ In this example we will obtain the following stationary velocity profile:
