This is a tuffy....

I want to model the motion of particles in a fluid, and I came across the equations to do it:

However, I've just gotten trough Alegra I, so it's greek to me (haha funny). Can someone provbide me with some code on how to use these?

wow

Hmmm

we don;t know cuallito. we are not experts on fluid dynamics.
what are you doing to want this? it's almost degree level stuff.

still, if you get anywhere we'll be interested.

You need more than some code.

The equations you are interested in are differential equations. I think they are partial differential equations instead of ordinary ones.

Finding solutions to such equations requires a lot more than writing some code. It requires writing a lot of code, usually after doing some high level analysis.

Since Fluid dynamics is a well reseached field, you might find help in a good math library. There might be some internet sites with articles.

The big problem you have is lack of sufficient background. You are likely to have trouble understanding the books/articles you find.

A typical math major takes some elementary and advanced calculus courses, which deal briefly with differential equations. Then he takes a course in ordinary differential equations. Finally, he might take a course in partial differential equations.

Some math majors might go off in other directions and not take any courses in differential equaitons other than the intorductory work in a calculus course.

At any rate, such subject matter is beyond the scope of this forum.

I have done a lot of work with the ordinary differential equations used for gravitaional computations, so I am probably way ahead of you in back ground knowledge. I would not be able to cope with the equations you provided without spending quite a few hours researching the subject matter and getting my self up to speed in this area.
