U can calculate all the fluxes and Jacobians say by using Maple or Mathematica. If U have Maple sofware, I can send U my maple file which computes the jacobian, eigen values, fluxe vectors etc.

Currently, I am studying the impact of CFL number on the numerical convergence and computational run time and I found that implicit method has difficulties to solve the Jacobian matrix, causing the required CPU time higher for convergence. One way of solving that problem is by using Jacobian-free method. But first, i am asking for one's good office to suggest me how could I start the studies from the Jacobian matrix calculation to have a better understanding on that. Thanks in advance
