 P: 145 Hi, I was wondering if Matlab was the sort of program I'd want to solve the Euler Equations (fluid dynamics). And if it is, I am sure this must be a very standard problem.. does anybody know of any tutorials for this sort of problem as I have never used matlab?
 PF Patron Sci Advisor P: 1,481 What are you solving?
 P: 145 Expansion of a gas jet. From what I know of numerical methods (which is not enough) I think it would be a shame to do it from scratch. The particular equation takes the form: $$\nabla\cdot$$(rU)U + $$\nabla p$$ = 0 (for the steady state case)

## Matlab and the Euler Equations

You can do almost whatever you want with Matlab. It has a limit in memory though. But for reaching that limit your computation should be very heavy.

What do you mean with the expansion of a gas jet? Don't be afraid about being more explicit, nobody here is going to steal your idea or your project. So please elaborate your answer a little bit more. Even in your post I see the words "jet" and "Euler Equations" which are two totally contradictory statements. They don't get along very well in fluid mechanics.
 P: 145 I had in mind playing with the gas expansion problem as a stepping stone to more interesting problems in plasma physics. With certain simplifications Plasma can be modelled with the Euler equations (see most textbooks on MHD).
