The Burger's equation is derived from the Navier-Stokes equation and includes the advective and diffusive terms. In this paper, a finite element approximation is implemented for the one-dimensional form of the Burger viscous equation. For this, the standard Galerkin method is implemented and compared with the Petrov-Galerkin method, which is the most suitable for problems with diffusive and advective terms, and different simplifications are proposed. Finally, four different schemes for time discretization are analyzed together with the influence of the Viscosity, time step and boundary conditions in the fluid stability. So that the conditions under which a shock wave is formed can be deduced.]]>
