The most thorough approach would be to take a class in engineering mathematics/numerics first. You can find these for free on itunes or other platforms. Without the mathematical background, you are in danger of becoming just a buttonpusher who learns the GUI of his solver of choice, without knowing the underlying basics.

So take a few classes on numerics, then I suggest you get some good introductory books!

Cheers!

Then I would suggest start by writing a 1D solver in the language of your choice for the lin, scalar advection equation using FD, FE, FV, DG, etc. That will help you understand the different discretizations and the strengths and weaknesses. Once you have that, think about extending it to 2D, or to Euler or Navier Stokes equations.
