Problem definition

 \frac{\partial u}{\partial t}+ u \frac{\partial u}{\partial x}=0

Domain

x \in \left[-5,10\right]

Initial Condition

u(x,0) = 
\begin{cases}
0 & x \le 0 \\
1 & x > 0
\end{cases}

Boundary condition

u(0,t)=0

Exact solution

u(x,t) = 
\begin{cases}
0 & x \le 0 \\
x/t & 0 < x < t \\
1 & \mbox{otherwise}
\end{cases}

Numerical method
