Help about equations

    I have to integrate numerically the next system of partial differential equations, in "r" and "z" coordinates (steady state, cylindrical coordinates):
    -Continuity equation
    -Momentum equation (with viscous and convection terms)
    -Energy equation (with heat transfer, convection, and internal generation terms).
    I heard something about Crank-Nicholson method. I have to implement this problem in Matlab or Fortran.
    Anybody know about how can I solve this heavy task?
    Anybody know about some web where I could obtain a method for solving it, and implemented in the software specified?.

    Thanks for answering.

    Does it need to be in Matlab or Fortran, or are those the ones you know how to use?

    It may be easier in Mathematica (my new favorite tool).

    To be honest, Matlab is my useful program. I've been working with it very usually. I don't know anything about Mathematica.
    This is the heaviest problem I've never simulated numerically.It is a part of a study of "deflagration initiation by hot jets".

    I'm looking for a website holding worked programs of CFD. Do you know anyone?. I'm too lazy to do the program on my way!
