The discussion revolves around solving a heat transfer problem from Suhas V. Patankar's book "Numerical Heat Transfer and Fluid Flow," specifically exercise 5.1, using the Upwind and Central Difference Schemes (CDS). The user is developing a Fortran program to address a bi-dimensional convective heat transfer issue with heat generation on a uniform mesh grid. Participants emphasize the need for more details about the user's progress and the specific challenges faced, as well as the importance of self-sufficiency in coding. The user has shared some code but is encountering incorrect temperature results and is struggling with the implementation of the TDMA method. Another participant notes the absence of an iterative loop in the user's code and expresses their own difficulties with the same problem, indicating a shared struggle among users with similar computational fluid dynamics tasks.
