This application mode gives us one dependent variable u, but in a l-D space
with coordinate x. Now we are in a position to set up our domain. This

Pull down the Mesh menu and select Parameters. By creating symmetry
boundaries, the endpoints become equivalent.

Now refine the mesh three times (120 elements). Now for the boundary
conditions. Pull down the Boundary menu and select Boundary Settings.
