Burger Equation with Riemann Solver in 2D case

伯格斯方程是一个模拟冲击波的传播和反射的非线性偏微分方程(Burgers' equation is a fundamental partial differential equation occurring in various areas of applied mathematics, such as fluid mechanics,nonlinear acoustics,gas dynamics, traffic flow. It is named for Johannes Burgers

The 1D Burgers equation is solved using explicit spatial discretization (upwind and central difference) with periodic boundary conditions on the domain (0,2). The 2D case is solved on a square domain of 2X2 and both explicit and implicit methods are
