iteration help

Mike,

This is an example:

x=sqrt((y-z)*2/r)

z= f*(L/D)*(x/2g)

f= something crazy with x in it

etc…(there are more equations with x in it)

So:

I say I need r to find x, but I need x to find z. I also need x to find f which is a part of finding z. So I guess a value for x, and then I use that value to find r and f. Then I go back and use the value I found for r and f to find x. I keep doing this until the guess and the calculated are the same.

Hopefully this helps,

D
