 February 26, 2007, 06:51 Re: nonlinear convection-diffusion #2 Lionel S. Guest   Posts: n/a Personally, I'd say that the simplest thing is to start from an initial guess (even 0) and then compute with one value and one unknown, for example x * x => x_prev * x where x_prev is the solution of previous iteration (or initial guess if it's first iteration) and x is the value that you actually compute. If things goes well, you should converge the the real solution. When the x_prev is same that computed x, you converged. Another solution is to make a linearisation by Taylor expansion, and then use the previous iteration as working point, from one iteration to anoter, as said above. Hope it helps
