it´s a problrm of convective heat transfer, bi-dimensional with generation of heat on a uniform meshgrid. if you know, it´s a problem from the book "Numerical Heat Transfer and Fluid Flow_Suhas V. Patankar_1980" - exercice 5.1.


the problem as to be solve using the CDS esquem and the Upwind esquem

You're going to need to show us more. What have you tried, and what kind of problems are you having? This isn't an all-you-can-eat code buffet, you've got to prepare your own meals.

Hi Giber,

I read your code and I notice that you were missing the iterative loop in the cycle. Im doing the same problem and I also have problems with my code. Were you able to finish that one? Im driving crazy with mine!
