Implementation of three methods; projection, SAT (Simultaneous Approximation Term) and a hybrid between projection and SAT, to impose boundary conditions for the viscous Burger's equation.
Choose one of the three methods to impose the boundary conditions and then run the script. The script will plot the solution to the Burger's equation, with or without a jump in viscosity. To have a jump in viscosity choose two different values on mu1 and mu2.
