Introduction - If you have any usage issues, please Google them yourself
The solver was made to solve the convetive heat tranfer problem (2-D steady elliptic BVP). Not only several schemes, which are ADI, checkerboard, Crank-Nicolson, Gauss-Seidal with SOR but also exact solution are also present. You can implement and compare the error of each scheme with analytical solution. The code was made at the LINUX platform. Let me know if you need assistance.
