TDMA and upwind scheme [theoretical calculation]
 

...................

which 10 books have you read from?

i think book by versteeg have a problem exactly like this solved in it.
and a book by peric has also a code for solving 2 convection diffusion problem. it is available online.

probably the wrong books.

is there any possibility that someone can check my calculation when i am finished? would be really really awesome and i would be very grateful!
